Advice please

I'm in high school and people my age are either dating, single, or are dating a douche. So I need advice as to what to do in order to confront a guy. Mostly bc 75% of the guys at my school are cute, 15% are taken, 2% are really nice guys, the rest are assholes. But out of the 2% I found a guy that I really like and enjoy spending my time around. Any advice?
