Nipples

OK - serious question! Why is it that it seems that only gay men or crossdressers like to play with their nipples?

I have watched loads of videos on here and it is mostly only in the gay or trans ones that they play with each others nipples! And yes, it gets me hot!

I love having my nipples played with or sucked and I am bisexual (I think)! I would love to hear from any other men, gay, straight, transexual who like having their nipples teased!

My wife is totally into playing with my nipples while I wank, mostly because as soon as I cum, if she continues playing with them I collapse into uncontrollable giggles! I can't help it, it's just the way it is!
