My husband is nearly 20 years younger than I am. He's very affectionate, responsible, and kind while very much into our relationship. All of which are selling points for me.
Originally, I wasn't into younger men, but I ended up pining for him when I first got to know him really badly... Eventually, I managed to get him alone and convinced him that I was into him and it turned out that he's wasn't just attractive and kind, but incredible in bed... He was beyond what I could have imagined, and later stood up for me against other men in life while taking on the responsibilities of being a proper male role model for my children, without even needing to be asked, since our sexual encounters were open-ended for him, at least according to me... But he has extremely traditional attachments to being a supportive relationship partner, without the traditional gender role restrictions that can be incredibly irksome with most men...
He's also essentially an angel, constantly working out the seemingly tremendous problems in my and my family's lives, and working hard with his intellect and charisma to actually fix major issues and really turn things around while remaining reliable and kindhearted.
Most recently, he's taken charge of the entire household, my children, and everything associated with me and my sudden heart attacks that I recently had last month... Almost every other man that I've been with prior would have either left me to die in the hospital, or not have perused doctors to help me as he did.
I'm essentially where I'm so in love and indebted to my husband, that I can't see myself with anyone else ever again. I'm completely smitten and would literally do just about anything for him had he only ask.
