Friends & Boyfriends

Hi

so recently i've been hooking up with this guy that i've known since i was about 12 years old (i'm 20) i haven't seen him much in the last 3 or 4 years but before that we use to hang out all the time.
He is also best friends with my best friend and recently we have all been hanging out together and that's how we starting hooking up.

My question is, is it ok to date someone who hangs out with your best friend? (the best friend is a girl) i mean his not even my boyfriend and already when she talks about going over to his room and hanging out and stuff while i'm away it already makes me feel weird, imagine what it would be like if he was my boyfriend. I know nothing would ever happen and i'm just being a girl but should i just not go there if i already know it might cause drama??
