This makes no sense to me. It's a gay sex scene! It is too an entrance, as well as an exit. It's not a scat fic! So it's not strictly an exit. And "anus" isn't very sexy when written in anal sex scenes. It again connotes defecation. However, I have used it, because of its specificity. I usually use entrance, opening, or hole. Also, "isn't actually meant to be an entrance" is very telling. Hmm, are you sure you're reading the right fic for your sensibilities? If you ever have a doctor probe your rectum, are you going to be able to tell her that? Or the medical technician who sends the camera up your butt to look for polyps? Yeah, just cause I'm referencing medical procedures, doesn't mean the point is lost. I'm trying to say that even the medical community sees it as an entrance, so what it is "meant to be" is how we use it. Wouldn't there be a one way valve if it was meant to go only one way?
BTW, gays aren't the only ones who enjoy anal sex. Where do you think some of us get our ideas from? I don't think I could write about something I know nothing about, even though you can substitute a women's "love envelope" into the same imagery.
The cock slides in [entrance], the cock slides out [exit], pushes in [entrance], pulls out [exit]. It's as natural and "meant to be" as breathing. Inhale, exhale.

Anyone else get horny from it?
