I have 160iq+ (maxed out the wais-IV). Being just a little different from your peers, especially as a kid, makes it difficult to socialize. And if you fall behind in the socialization game you are at a severe disadvantage. Nobody wants to talk to the 12 year old that acts like a 10 year old. People REALLY don't want to talk to the 16 year old that acts like a 12 year old.
That alone is already enough to fuck someone up, but there are more men than women with high IQ. There are 1.83 times more men than women above 130 IQ, and 4.3 times more men than women above 160iq. High IQ interests/hobbies, groups, classes, and peers are going to be mostly male. That's on top of high IQ being a rarity in general.
Outside of high IQ people (who can be annoying to interact with in their own ways), dumbing yourself down to talk to normies is exhausting.
You can't talk about certain things, you have to pretend to not know things you do know, you have to actively rephrase things and dumb down your speech pattern, but you have to do it carefully. Too little, and you come off as a weird sperg. Too much, and you seem patronizing or just retarded. You have to constantly gauge the other party's intelligence and knowledge and adjust to match. It's a skill that takes effort to develop.
Lastly, despite having a relatively high libido, I'm not all that motivated to have sex. I think a lot of intelligent people are the same way.
