It's true that *some* women may feel pleasure at the germane activity of inoculating semen through their oral orifice. It's also true there are women who like anal, who like all the physical abuse men can imagine putting them through.
They are not, by far, the majority of them.
You literally have no idea about this, you just made that up. You have no evidence whatsoever and no grounds to make a statistical claim about majorities and minorities. Anal can be fun and easy and doesn't have to be painful. Swallowing semen isn't any different than licking a ****. It tastes funny, you get used to it.
The physical equipment doesn't differ that much. I would wager that 95% of women (and heck, men) would enjoy skillfully done anal.
For perspective, by far the most commonly reported sex fantasy among women is the rape fantasy. This doesn't mean women want to be raped, but it should give you some insight into the fact that women are just about as voracious and ****ed up as men are, they're just taught to be quieter about it.
You just have to look at the cringed faces they show in these movies while trying to perform nicely with the yellowest of smiles as ordered by the director. That means that not even the self-selected group really likes it that much.
NGTM1R already explained in good detail why the act of making porn is so unpleasant, and it has very little to do with the acts performed and a great deal more with the conditions. Go back and read his post. Nobody's arguing that studio porn is somehow good, you just picked terrible reasons to argue it was bad (namely, that the acts depicted were inherently degrading or wrong).
The rest of your post is a waste of words in light of what NGTM1R already delivered, except the following:
This may be sex, but it is horrible sex.
See, this is a much better point than 'it is inherently degrading hurr durr', and one I agree with.
There are many genetic reasons for these different attitudes, and I'm sure I won't need to list you them, for you are a smart general.
The reason you can't list them is because you don't know what they are. These alleged genetic reasons are actually mostly smug patriarchal fantasies that get demolished when you learn anything real about evolutionary psychology, instead of just swallowing the horse**** they give you.
We have no ability right now to precisely separate the biology of sexual behaviors from the cultural. Hypotheses have been advanced that women are biologically hardwired for group sex with multiple male partners, whereas men are hardwired to be aroused by watching women have sex with other men. But these hypotheses are unfalsifiable and should be treated as such.
Basically the takeaway here is that you are a virgin. Once you get into a loving relationship you will hopefully have a chance to explore a bit and become a bit more comfortable with sexuality. I'm also detecting the residue of a religious upbringing here, I think?
