He mentioned nothing about making her cum from anal - which I have a hard time believing actually occurs. There is nothing there physically which would make a woman cum. If you are using clitoral stimulation then you're making her cum via clitoral stimulation - nothing to do with shagging her up the arse. All you are doing is causing rips and tears in her rectum, which may go on to cause fistulas, you may be infecting you penis with faecal bacteria if not using a condom, and she's at risk of incontinence if anal sex is indulged in frequently - an acquaintance who's partner is always at her anally is facing having to have a colostomy bag due to excessive anal and rectal damage due to 'pounding'.
Nice to see you have respect for your fellow human being. Thank you also for encouraging a practice that is likely to humiliate, agonize and leave many women physically damaged in the future.
Might I ask your thoughts about women who actually enjoy anal sex? Ones who do it because of the sexual satisfaction it offers them? As a person who seems well versed on anatomy, I'm sure you know all about how a woman becomes responsive to anal penetration after a few orgasms, due to the fact that the walls of her rectum become looser, thus allowing the cock to press against her gspot if fucked properly. If so, then you are aware that a woman can get an orgasm through this type of penetration.
As for your last comment, personally, I feel as though you are looking to attack purely for the sake of attacking. I have quite a bit of respect for humanity. Sadly, it sounds like you've had some negative experiences with anal sex, and if that's the case then you are completely welcome to feel that way. However, don't make the assumption that the act itself is hurtful, degrative, and meant to damage a person (male or female) as people can have anal sex without it being about hurting them. "Pounding" as it's been named, is one way to have anal sex. Is it the only way? No. Again, it depends on what both parties wants.
I would assume that the OP has/will take the time to gauge his partners response to a cock inside her before he start pounding away.
