Will guys ever find me attractive?

I am 15 years old and a girl. I know I am very young but most of my friends are already dating. I spend most of my time playing video games and watching anime. Most of my friends are boys but they are all only friends. Besides I don't have any strong feelings about any of them but I am kinda worried because I don't wear makeup or do any "girl" stuff so I don't even know if people see me as a girl. I am pretty sure I am not lesbian and this is nothing that a stay up all night and think about but I really don't want to end up as a lonely cat lady :)
