How to convince a guy to date me and not be friends with benefits?

My crush apparently only wants to be friends with benefits with me (we’re both 17) and I don’t want to because I actually have feelings for him. We haven’t done anything besides make out but he treats me like we’re in a relationship, he’ll kiss me goodbye and cuddle me in public and stuff and we haven’t actually done anything sexual.
but he told our friend that he wanted to be friends with benefits and that he doesn’t want a relationship before schoolies (schoolies is just a holiday that you go on with your friends when you graduate high school and everyone gets drunk and has sex with anyone).
He said he’s not trying to lead me on and that he doesn’t mean to kiss me and that’s there just “so much sexual tension between us” but I don’t want to do stuff with him unless he’s in a relationship and I can’t get over him so I’m lost with what to do
