they don't have prostates...

I'm a straight male

Darn lol

But, as you say, sex is not what defines your sexuality. I don't believe that, if you currently don't have the slightest attraction to members of the same sex, if you actually tried having sex with men (I think you're a guy right?) you would suddenly discover you're attracted to them. I honestly don't believe it works that way. Especially if you don't have any socially imposed repressions regarding your sexuality. I can imagine a deeply closeted person being drawn out by physical contact, but something has to be there to begin with.

It's actually very painful for them*, and can cause infections through microtears in the rectum, and fecal incontinence. Fun facts!

* To start, but regardless, any enjoyment of it from a woman comes from making her partner happy.

Yep, I already knew all that... I'd say with one of my exes, we had the idea of doing it maybe 10 times or so, and only twice we were able to actually do it. Cause it hurt her too much... she was really into ass play stuff so i think it intrigued her. the only time it was really pleasurable was when we were stoned out of our minds and she used the vibrator too. Basically I see no need to put it in anyones ass when there is a better place to stick it just a few inches away.

Well the general idea is that a tighter hole feels better.

Eh, not when you can hardly even get it in.

Sodomy on the internetz.

Fuk it, I'm gonna call myself a Bi-.
