What does it mean to be a beta.

I'm a beta. I'm 37 and i'm almost virgin.
I had more or less 15 sexual intercourses with two girls in my lifetime before being dumped.
Most of (the few) girls that i approached rejected me. I'm quite cute and wealthy. It's not about appearence or social status. It's genetics.
I don't crave for girls anymore. My sexuality is entirely based in masturbation. I don't even look for nudies. I don't deserve pussy or tits, not even in picture. Only clothed girls. I don't look tits and ass a lot. It's Alpha stuff. I prefer feet and armpits.
My favourite fap material are pics stolen from my female friends socials.
They don't suspect what a kind of stinky pervert i'm. They consider me a nice guy. Just a friend, of course...
