I really like a guy i met.?

know him already but not really well we never had much conversation. well as it happened everyone else at the party fell asleep or went home so it was just me and him.we ended up going to bed together but we were just talking.ended up having a bit of a kiss and a cuddle..but nothing else and he didnt seem to try anything.he was gonna get my number but we fell asleep cos we were wrecked and he left with his mate eventually and i wouldnt wake up!. i kinda like him but i dont bump into him that regularly although know his mate and brother a bit.do u think i should pursue it abd how do i do this in a fairly cool manner? thanks in advance.
