Sex with a friend?

Nat • I'm 17, Bi, currently in yr 12 and studying Art!!

So I have a male friend who I am sexually attracted to but not romantically and in the past he has subtlety asked to have sex but I've never done it and wasn't ready so I said no. We never stopped flirting or lost the attraction towards each other and now I'm ready and really want to do it. (I'm 16 almost 17 btw)

But is it bad/ what's everyone's opinions on having sex with a friend (and more specifically having your first time with them)
