Needing Advice!!!

Hey, I'm almost fourteen and in high school, and I'm always feeling really lonely and have never had a boyfriend, or my first kiss. :-( There's this guy I like, but I'm not sure if he likes me. We talk on Snapchat a lot, and according to my friends, he flirts with me a lot. I want to get him to ask me out, but I don't know what to do, or how best to get his attention, or see if he's interested. Any thoughts? Tips? Advice? Anything?
