Why is it so hard to find another guy who wants more than just sex? Is something wrong with me?

Almost every gay/bi guy that messages me on Facebook, dating apps, etc, just asks for nudes, then when I say no they just stop talking to me. Then a month ago I started dating a bi guy, he played me and dumped me after just a few days and found someone else. I'm pretty young (senior in high school), but I feel like giving up on love, all I find is guys that just wanna fuck me and leave lmao.
