It is to my eternal frustration that my ex could never do anger sex. In fairness, you couldn't really argue with his reasoning; when he was pissed off at me and upset he hated me just a little bit in those moments and as a result found me really unattractive right at that point, so the last thing he wanted to do with have sex with me. A perfectly valid and fairly unfaultable perspective you gotta admit,
But god damn it anger sex is hot and solves issues.
Imagine it. Your boyfriend, girlfriend, asexual limpet, whatever pisses you off somehow. You're screaming and yelling at other. You'd really really like to introduce their face to your clenched fist right now. Or smash their head against something. Nobody would notice a dead body under the floorboards right? They make you so mad you wanna kill them, cut them up, and then jump on all the pieces until there is nothing left but pulp because sometimes they can be an inconsiderate jackass. So you grab 'em, and you hurl 'em against the wall. And they cry out in pain. And you slap them across the face and drag them across the room with far more force than could ever be necessary and you really dig your nails in and bite down on their skin making sure to sink your teeth in....
And the next day, when your horrified co-workers ask how the hell you got all those bruises, you reply "Oh I had anger sex with my boyfriend." And suddenly, it's TOTALLY FINE, and everyone understands.
Because anger sex allows you to beat the shit out of each other in a socially acceptable manner. Of course I'm not condoning any kind of abusive relationship, physical or otherwise. But sometimes, you really don't want to give a shit about their happiness, sometimes, you really want them to be in a bit of pain, and even more, you want to be the one causing it. And when you both wake up with bruises on your hips and your ass from where you were slamming against each other so hard the bed probably broke, you'll both have a smirk on your face, because you did that, you caused them that pain and every time they wince slightly for the rest of the day it's gonna make you feel better about whatever the hell it was that you can't remember you were arguing about in the first place. Plus you got to have some fucking fantastic mind-blowing sex in the process.
I totally understand why my ex wouldn't have anger sex with me, but man did that piss me off to the point where I just wanted to fuck him more :P
