When it comes to nipple play for men, it seems to be a taboo subject. But when it comes down to it, men's nipples are just as sensitive if not more so than females. I'm sure that more men enjoy it more than will admit to it. But I admit it, and I'm a VERY straight man in love with his wife, and here is my story.
For me, my nipple play obsession started when I was 12. I would play with my nipples and masturbate a few times a week, so my body learned to require nipple play to cum.
My first sexual experience occurred when I was 19 though we never had sex. It was a lot of nipple play and masturbation. My second experience was when a girl started to play with my nipples on her own and liked what it did.
When I got married, my first wife played with my nipples for a little bit but didn't like that I needed that kind of stimulation in order to climax. Sadly our marriage ended for other reasons.
But I got another opportunity. My current wife is all about performing nipple play on me and has never had an issue with it. In fact, my nipples were/are an obsession to her, for which I'm thankful. If my wife isn't playing with them when I cum, they are brushing up against her breasts which pushes me over the edge.
All I can tell you is that when my nipples are rubbed, I can feel it in the deepest part of me. It is THE most intense feeling that I have ever had other than my orgasm itself.
I know that a lot of men associate nipple play with being gay. But I've read that A LOT of straight men love it, and their wives LOVE to give them that pleasure with their fingers or tongue.
I can tell you that I will ALWAYS love nipple play done on me for the rest of my life. I would love to hear from other men about how they like or dislike nipple play and from women who enjoy giving it to their men.
