I got bullied and had zero people show sexual interest in me too. The bullying largely died-down when we teenagers matured, and by strictly sticking to : shut up if you have nothing nice to say about people, no matter the context or who is there to hear it. That's for school. After school I didn't spend much time with people.

Yes people get more touchy and friendly when you get fit. ( Women doing those small random physical contacts during conversations. )

I was so spiteful of that when I was younger. ''Oh people are so shallow, I am a good person and I'm nice to people!'' Well humans ( me included ) are visual creatures hard-wired to find certain trait attractive and others repulsive to make them choose fit mates. Too bad. Resenting that won't change it.

So I put my energy into hobbies and I accepted humans aren't that complex : if you want to be sexually desired, make yourself sexually desirable on aspects under your control.

Some of my hobbies I can share with people, that's nice, but I'm only comfortable if the hobby is the center of attention, not other personal stuff normal people make small talk about.

I don't care that much for dating, so I don't date either. Not that anyone hit on me, and I never hit on anyone.

Still, getting fit alleviates depression. Pills didn't have a positive impact for me. Daily exercise did. People wanting to be friendly to you more is a bonus, but I'm a loner anyway.
