Back in the mid '70s, I had a girl friend, well sort of. We'd gotten together for a while in the early '70s, she dumped me then, on halloween night of 1976, we ended up on the floor of a platonic female friend's apartment. We started having sex. Suddenly, after sucking my penis for a while, she said, "I want you to turn over on your knees." I did and suddenly I felt her spread my butt cheeks and her tongue go up my ass. Way up inside. She licked around my anus then stuck her finger up in me and started to move and wiggle it around. It did feel really good. After a while she stopped and I asked her to get on her knees and returned the favor. When I get really "turned on", sexually, I am liable to do all sorts of stuff with a woman if she wants to do that (within limits - frankly, I would not want another guy involved and I would not participate in anything abusive). Anyway, when I was licking her butt, I wanted to try to find some sort of lube and fuck her butt, however, I decided against asking for that. By the way, we did gargle with some mouthwash when we got through. Later, after we were married, just so this former girlfriend would not be the only one to have done it to me, I did ask my wife, once which she was doing a handjob on me, to stick her finger in me and she did. I have occasionally stuck my finger in my wif's butt when doing "69", however, I've never licked her butt and she hasn't licked mine. I would suggest that anyone involved in that sort of activity gargle with some Listerine or other antibacterial mouthwash afterwards just to be on the safe side.
