20 is young af. I was never expecting to have sex at that age too, but then I suddenly lost mine at 21 and have been multiple partners since then. Even after losing virginity tho, there were still long periods where I did not have sex between sex partners. You start to realize, the idea that you need to lose your virginity "early" is some extremely dumb societal bullshit. I've been victim to it myself in the past. But it literally does not matter or mean anything. Not only are you still rly young, and the vast majority of the world is still virgins at that age (srsly, go live in more conservative countries), but it doesn't matter even if you were 30 and a virgin.

Focus less on it, and more on building yourself in other areas. That doesn't mean you shouldn't make yourself available for people to potentially sex you. Do that, and groom yourself, and get out there and just try being friendly to everyone. But this shouldn't be something that consumes you this deeply. Focus on becoming the person you want to be, whether that means getting a job, or doing whatever else.
