MOWO needs to get a book like my beginner bottom bible - The Ultimate Guide to Anal Sex for Men. Don't know the author, and I'm at work so I'm not game to Google it. It's a good all-round guide, and is very open about the fact that guys can bottom to other guys, girls, or just to themselves. Seriously, though, it's being sexually attracted to the same gender that makes you queer, not liking anal stimulation.
MOWO might even enjoy anal in a nonhomosexual way. My wife and I love to experiment and I told her I'd like to see her with another woman (she's been tempted ut never actually been with a woman before). She said she'd love to try it but I have to have anal with another man while she watches first. She's been "practicing" on me with various toys and it sends the prostate through the roof! Give it a shot, you'll like how it turns your wife on!
There have been accounts of people who get off on watching other people participate in the fetish.
Or maybe that's just a Japanese thing in their version of it, called "ntr" (an abbreviation of their term for it, "netorare")?
Or would that be a different fetish altogether, maybe called "ntr voyeurism"?
