how to get a girlfriend

i (17m) really want a girlfriend (or bf, but for the sake of this post just think gf). but i’ve never been in a relationship before and i don’t want to just randomly add people on snap or something because i want someone who is serious and actually cares not just a person who snaps me for attention and fun. also another problem is that i’m a trans guy. i pass decently well but i just don’t think anyone would ever actually want or like me. but other people i know are getting into healthy relationships and it makes me really want companionship in that way. so how can i get a girlfriend or increase the chances of someone liking me?
