Casual sex is pleasurable and since Humans mostly learn through repetition,it can be addictive. If you live a life going through different pussies then you are gonna want to keep having different pussies. This extends to women as well except pussies = dicks.

Its not strictly "casual sex" but like the same shit can happen with a couple that fucks a lot too. They can fuck a lot and then need to male a household but they need to fuck so much and so often its not within their reach to make a stable household

Discipline is important. Otaku are kinda retarded about it though to be fair by just shitting on the idea of having sex at ALL
