Should i go out with this guy?

well, he's on my bus(that's how i know him) and he's a year older than me. my brother is in his grade and my brother is the weird,dangerous,outcast and he gets teased because he acts all tough when he's really not. anyway, that gives me an excuse to talk to this guy. we are from extremely different worlds. i'm the good,quiet,cute,nice,soccer player. he is going to be held back next year,he gets in trouble a lot,he's loud,obnoxious, and has smart *** humor. one day, i didn't know my soccer practice was cancelled. i went to the field so confused. i saw him and asked:'hey kale, on the announcements, did you hear anything about girls soccer practice today?' he said no. he was hanging around the bleachers because he ditches detention. so i try going back inside to call my mom to pick me up, since my phone died. the school was locked. i go back to the bleachers to do my homework and wait for 5:30(the time practice would end) after about 20 minutes it starts to rain...really heavily. so kale tells me the equipment shed is unlocked and we could wait there. so we go there and it's dark. so dark, i try to find a place to put my bag down and we crash into each other. everything got so intense we started making out!! for like 10 minutes!! until the rain stopped and we slowly walked out not saying anything. i'm confused! should we go out?? or leave it at that and remain friends?! i like him a lot but i'm not sure if he does back. help!?
