I enjoy hooking up with married men. We both know nothing serious is going to come out of it and we're fine with that. There are three in particular that I remember:
A fun-loving construction worker, married with kids, who was always a lot of fun to get with. Told me the story about how his wife found about his desire for men a few years back...and he tried to stop, but just couldn't.
A compassionate Spanish-Catholic father, with kids about my age...told me about the role religion had in his life. Really good kisser. As we finished up and he was leaving, he gave me fatherly advice about how I should be careful as there are dangerous people out there.
There was also the geeky midwestern bear father who just discovered how much fun it could be to have sex with other men. We spent awhile talking first to calm his nerves and then had some of the best sex I've ever had.
