A couple of things are true about me and my sexuality, and have been since I first discovered that touching things "down there" felt kind of good.
1. I like women. I fantasize about women. I like looking at naked women, and get aroused by looking at and thinking about them. I have had a lot of sex with women and enjoy it immensely.
I don't fantasize about men. I can look at a naked man and his penis and not get freaked out, but it doesn't arouse me. I even admire the male form, especially a well formed one. It's just that having sex with a male does not appeal to me.
2. I like butts - I am fascinated by them and like looking at them and playing with them. I play with my own, and enjoy it immensely if my partner plays with mine. I have a rectal thermometer fetish, which I have had since before puberty. I love seeing a rectal thermometer sticking out of a nice bottom. But mostly I enjoy having a thermometer put up my rear. I also have inserted all manner of things up my butt - enema nozzles, anal beads, small dildos, butt plugs, suppositories, etc. and love the sensation of something sliding past my anus. I have had my prostate massaged by a lover while masturbating and had the most intense orgasm of my life.
So, I have a lot of experience with anal play. I am a man and enjoy having things put up my butt......and I'm not gay.
Society has done a number on men by reinforcing the stereotype that only a gay man likes anal play. I'm glad I didn't worry about the "gay thing", because I would have missed out on a whole lot of fun and pleasure.
Bottom line (pun intended). Play with your ass. That alone doesn't make you gay. And if you are gay, who cares? You shouldn't worry about it. Just my humble opinion......
