As someone who used to think they were a man, and who felt that as a supposed man they had a “role” to fulfil in wanting sex whenever it was an option, I can absolutely back this up. I have caused myself no end of damage because I thought that wanting sex was the default state and I should jump on the opportunity whenever I could.
Sex is great. Lots of sex is great. But it’s okay to not want to have sex, and it’s not worth the psychological damage to have sex when you don’t want to have sex. It can be like sexually assaulting yourself.
