I know you only asked the married guys to weigh in- but I'm intrigued by the subject. Of the women I slept with in my life, all of them willingly and happily gave blow jobs except one. To tell you what sort of person she was- Her best friend, a gay man, referred to her as a "cunning manipulator." His assessment of her personality was spot on- as I finally learned. She seemed incapable of true intimacy in or out of bed -so I left her. I think if you love someone- you want to please them and you get pleasure from their pleasure- because you love them. Therefore any woman who cares for you will take care of you- and my advice to guys is to give back- as often as you can.
