The other day I had a stream on while working on things, and the beginning of it was just talking to chat while waiting for people to show up. At one point, they started talking about ragefucking, and argument sex. They then said that it is never actually a good idea, and I started thinking about the science of it.
Ragefucking is a trap. Full on Admiral Ackbar trap. When people are fighting, it stimulates the brain to create similar endorphins that would occur when we're turned on. And because we're that worked up, we look at the other person for the same relief we would want when we have too much stress, or need comfort and catharsis. That physical barrier is broken, so both parties let that be an instant response.
Afterward, all the bonding chemicals happen, and bring them back together. It's probably the reason why most of the couples who constantly split and get back together do so. They know they're incompatible, but there's that anger and then sex brain chemicals that wind up tricking them into staying close until there's so much animosity that they're just done.
Sex does so many weird things to our minds. A lot of people don't think about what is happening to them when they're so driven by emotion.
