BOOTY CALL?!?!😩

Okay, so, there's this guy in the year above and I've alwayssss thought he was good looking but he's popular and I just knew nothing would ever happen. But recently he's been snapchatting me a lot and asking how my day has been and calling me gorgeous etc(he has never asked for pictures or anything like that) he has tried flirting with my best friend before so this is why part of me is worried that all he wants is sex and that's it. He says he hasn't had sex loads and with only like 3/4 girls but he's so popular and good looking I'm worried all he wants is sex. Someone help? I would ask but I have no idea what to say!!
