It kinda stopped bothering me after 23 or so. Now I'm 26 and I don't even feel sexual attraction anymore. I don't even masturbate, I just work, and in my free time I stick to my few autistic hobbies. I used to be more social but a lot of the people I used to hang out with weren't really my friends. Now I barerly socialize but when I do it's more fullfilling. My life is not perfect but it's pretty comfy.
tl;dr don't kill yourself too fast, I think it gets easier with time
