I genuinely cannot imagine that I will ever have a relationship or sex with someone

I'm 21M, a virgin, and I've never been in a relationship. At this point, I honestly struggle to even imagine what it would be like to be with someone. I know people say I'm still young, but the whole concept feels completely out of reach for me.

Being neurodivergent has always made this stuff infinitely harder for me. It’s not like I never tried anything. But almost every time, things just fizzled out or fell apart before they even truly started, which only reinforces this feeling of hopelessness.
