Spontaneous, age 19, I was chatting to a friend while she showered behind a curtain. She pulled back the curtain then she invited me to join her...

though im thinking there must have been some sexual tension between you to prior....

I. Was in my early 20,, 22 to be exact. And I had an older male mentor friend who asked me if I wanted to learn about self stroking pleasures. And what it was like to enjoy a M2M massage. As we got naked. I couldn’t believe at how turned on I was getting. He had a very beautiful, long. thick, fully cut cock. It was the 1st guys cock that I ever saw hard.
Well to say the least, it was the most amazing experience being given a long, edging and teasing HJ. He took a very long time to make me Explode. And when I did, I shot big loads of Cum all over my stomach and his hands. My whole body was shaking!

Mine wasn't a full on same sex situation but I would have been about 14 when my best friend (female) and I was messing about and she had pinned me down on the floor where she proceeded to pull down my knickers and massage my pussy. Very weird because she never let me return the favour.

I’ve always wanted to play with another cock, and maybe even suck it. I don’t really find guys sexually attractive but I feel like I do have a type lol because when I picture blowing a guy ( definitely pops in my head from time to time ), it’s always the same kind of guy. I also think that I’d have no issues if I was group of guys, can’t see myself fucking/getting fucked, but jerking off two while blowing a third sounds like fun to me. I think I’m really into sexual situations.

Has not happened yet.

Well,

I didn't plan it myself, But I think the other guy did. He ask me to stay over with him one night, And later that night, He pulled out some xxx mags. I'd never seen anything like them, Well, being young men our dicks where hard in matter of seconds with us looking at the xxx pics in them of men and women , and then the Bi Mag came out!! showing a guy on his knees sucking the other guys cock! I was like WOW!! We can do that too!? He said sure and pulled out a beautiful big hard dick , Gosh! I can see it now so clearly! pre - cum was oozing out of the p-hole as I dropped to my knees as the guy in the photos. Somehow I new it was what I wanted to do and Did!

He showed me all the other ways to enjoy being a Bi Slut. with his big dick every chance he got after that night, I was 16-17 best I can remember. He was 19. Loved it then and still do today.

Been married 6 months, I’d always wanted to suck a dick and get my ass pumped. Wife was well aware of what I liked. Had a friend over and somehow we ended up naked. We were both pleasuring my wife when she pops up and asks the guy if he wants to fuck my ass. He said yes!!! Omg, we sucked on him together then I continued to suck while she licked and prepped my ass. He slid in, I was in heaven. I felt the hot gush of cum inside me and I’ve been addicted to it ever since. We played off and on over the years until she snapped, almost got divorced but we didn’t. Nowadays we’re both paranoid about disease or I’d be a cumdump for sure. I love women, love my wife, don’t find men attractive but I have an anal fetish and the best anal toy is a penis.

My firs time was during a mmf when I was 41 and It wasn't planed. I knew the husband was bi and wanted to suck my cock, They said the was no pressure at all to let him and I didn't have suck him back. Well, I let him suck my cock and I did suck his as well. It turn out to be a great night.

WHen I was around 15 me and a friend would masturbate together. Not sure if that qualifies exactly as Bi-sexual. My first real experience was in college, probably around 19-20. I had a female friend with benefits and we would get together occasionally for some great sex. One night I came over to her apartment and there was another guy there. She asked me if I would have a threesome. Yes!! At one point I was laying on my back while she sat on my face and simultaneously was giving head to the other guy. Next thing I know he's going down on me while I'm eating her out! Later in the evening when she was giving him head again she asked me to join her. I wasn't sure about it, but since he had already gone down on me, I thought it only fair. We took turns going down on him until he busted his nut down my throat. It was an amazing feeling! DId a few more three and foursomes throughout the course of the school year and it would often lead to some bi-oral. One time I let a guy fuck my ass, but I didn't really care for it. I never reciprocated as anal is not really a turn on for me.

My first bisexual encounter was quite random, I was showering nude in a gym locker room that had the older style group showers. It was before closing and hardly anyone was using the gym. Another guy came in while I was showering and turned on the shower next to me. My cock was hard since that tends to happen when I am showering. My bald cock was soaped up as well.The guy was looking at my erect cock and moved his hand closer. I knew he wanted to touch it, so I said what the hey and let him. He began stroking me and it wasn't very long before I shot a long ropy wad of cum from my pee slit. The gym was closing so I left the shower room. As I turned around I saw they guy masturbating in the corner of the shower!

A long-time friend started sleeping naked when he was in high school. One time I spent the night there, I got really curious so I reached over and touched his cock head. It was rigid! But he didn't react or move, so I didn't do anything more that night ... but then a few weeks later I slept over again. This time, he was on a palette of cushions on the floor and I was on the bed. I looked over and saw how hard his dick was, so I said something lame and switched from the bed to the cushions and got out of my tightie-whities at the same time. It didn't take many seconds before we had hands on each other's cocks and were stroking. Soon after, he was sucking mine like a champ, so I don't think it was his first experience with another guy. Maybe it was planned on his part?

The closest that I've come to having a lesbian moment involved having a girl crush on a girl guitarist in some band. The second time that I went to see them, my crush was gone.

Best of my recollection - Was spending the night with a school friend, early teens. We got in a corn bin of shelled corn, and were wrestling around. Next thing i remember we were sucking each others cock. We kept it up a few years, adding a couple other school friends, until we found the pleasure of pussy.

My first bisexual experienced happened when I was 19. I went over this guys house with some friends as he was a hookup they had for weed. I had never met the guy before that night. We hung out and smoked some weed as was normally done so the neighbors did not get suspicious of quick in/out visitors. The guy was sitting next to me and sort of rubbing up against my leg and I really didn’t realize what he was after. Most likely because I didn’t know he was gay and we were pretty xxxxxxxxxx. Then my friend and his girl decided they needed a run to the store for some cigarettes. They asked if I wanted to go or wait for them to get back. I told them I would wait for them. They left for the store and the guy started rubbing my leg through my jeans and slowly worked up to my crotch and start rubbing my cock through the jeans. My cock started growing and I had been going through a dry spell with the ladies so I asked him if he wanted to suck it. He said let me go lock the door I’ll be right back. I stood up and pulled down my jeans and boxer while he locked the door. He came back and was shocked I had my pants down and hard throbbing cock out. He immediately put it in his mouth and started sucking me off. Shortly after my friends showed back up so luckily he locked the door. We didn’t get to finish and I had to stuff my rock hard cock in my pants and pretend like nothing happened. My friends never said anything. We left shortly after and they dropped me off. After I got back to my house I was horny and very curious so I got on my bike and road back to the guys house and knocked on his door. He was surprised to see me show back up. He ended up finishing what we started and after that I asked if I could fuck his ass which we did as well. Off and for the next year we played around and then I went away to school. Have not been with another guy since but hope to someday.

47 and was definitely planned

Only one experience, so far. I was about 40 and responded to a CL ad. I went to his placed and we 69’d. I loved the feel of his cock in my mouth and would’ve preferred to not 69 so i could focus on his cock and make him cum. Neither of us orgasmed. We just stopped and I left. I really want to suck a cock again and this time swallow cum.

Remember it like it was yesterday. When I was dating my first wife, we spent lots of time nude with friends sunbathing, and hot rubbing. She had dated a girl in college ( 1985, pretty early then) who we hung out with. She was dating a guy ( wasn't the one) so we double dated all the time. One night her friend was over, the 3 of us drinking, and a fantasy of mine was satisfied. After a few more nights with her, my gf said that she wanted to try 2 guys. I had to say yes. The guy who it was with was someone she was close to in college, and "S" had also been nude sunbathing with us.
The night arrived, and we had a great time double teaming the gf. We all had cum, and were just laying in the bed. S leand over, and started sucking my cock. I was enthused. He had me cum in his mouth and I then sucked him til he came. The gf was ecstatic!
That was the first, many times after that, he and I even teamed up on a girl friend of his a few times.
Later the second wife and I had a regular couple that we would party with. Great experiences and memories.

Over thirty years ago, I went to a new schoolfriend's house after classes. But he wasn't home, even though we had arranged to play video games. His mother was working as was his older brother, but his dad was home early. The father, Gio, was a laborer. Born in Europe, he spoke with a sexy accent. He was a handsome man in his fifties, with bulging pecs, biceps and broad shoulders. Gio caught me eyeing him and winked conspiratorially. Since this was an unseasonably hot September day, he was shirtless as well as barefoot. The sight of him overwhelmed me, and I couldn't keep my eyes off of him. He grinned and patted his bare ample belly, saying he loved his wife's cooking, but she was lacking in other ways. He walked toward me as he began fiddling with his crotch. Gio took my hand and squeezed it around his hardening dick. Then he pushed me to my knees and said, "Lungo tempo non ho fatto cosi. Non dire niente a nessuno¹," he growled, as he rammed his uncircumcised cock into my mouth. This was the beginning of several years of me providing the relief his wife would not give him.

¹"I haven't done this in a long time. Don't say anything to anybody."

My first experience was when I was a teenager and at a sleepover at my buddies house. Long story short we're looking at porn and super horny and he offered to blow me. At this point in my life I had to never cum. His warm mouth on my cock didn't take long for me to shoot my load. He went to the bathroom to spit it out when he came back I pretended to be asleep as I lost my nerve to reciprocate. Things between us was a little awkward after that for the next few months.

My second experience was 16 years ago with a married couple and the husband asked if he could suck me which I let him do and while his wife watched. His wife ended up joining in and sucked my balls while he sucked me dry. I did not blow him or even touch his cock but we did double penetrate her pussy & ass.

I have yet to suck or touch another cock but I do sometimes wonder what I'm missing (bit I'm also nervous about catching a std)

Not sure if it counts as a bi sexual encounter, but when I was 15 and on a school trip to Paris my friend decided to have a wank. There were 4 boys in the hotel room and a girl that snuck in. I had just watched the girl, my friend Vicky have sex on the floor next to my bed. I was very horny too after that! Everyone was asleep apart from my friend Martin and I. He got his cock out and began wanking, I got my dick out too and we wanked ourselves off. His cock looked good. I shot my load quickly, it was very horny.

Another time my friend Steve took his clothes off for me in his bedroom when we were 16. I didn't know what to do, so I left. Wish I stayed now.

I've wanked for guys online line, but never anything physical.

I’m definitely open to it, just haven’t encountered the right situation. Being married and the wife not being interested in threesomes / foursomes (despite being in invited into two different ones by friends when she was younger) doesn’t help.

My 1st bisexual experience was with an older male mentor friend when I was in my early 20’s. He gave me my 1st M2M HJ and later my 1st M2M BJ. Both experiences were amazing!

Yet to happen.
I grow more and more curious day by day. I want to know if I like it. Any one wanna give me a hand ?

I was at a party when I was 19, drunk and made out with another girl in the bathroom lol. My bf at the time was furious

Wow, it was a long time ago. It all started with kids in the neighborhood at the age of 11 or 12. The usual show me yours I'll show you mine. Which of course led to touching, and a little behind the scenes of just lick the head! Well I also had a cousin and we realized at 14 or so we liked to show and play, which turned into our first blow jobs. The fun all ended when the cousin moved away, but the enjoyment stayed with me. Fast forward 40 years, another couple we have been friends with for years had a good night of partying, got into a little strip poker and I lost and was dared to suck his cock. Needless to say, I jumped at the chance. He was suprised as all hell! Well a couple of days later he said that it was the hottest thing ever, and he wanted to reciprocate! Long story short, we have been enjoying each other for 10m plus years now.

I responded to a CL ad to get blown by a couple. I walked in and she was already sucking another guy's dick. I sat down and he sucked me until I came in his mouth, great head. Afterwards, he started sucking the other guy and she sucked me. Also great head. It ended with me watching her get spitroasted and jerking off.
