Is he turning into a fuck boy?

Miranda
I met this really cool guy through my friends and he's been acting shady lately. 
Yeah we had sex a few times and I did kind of Tell him no sex just to see his response. 
But he was super pushy and kept trying. I pushed it to the back of my mind and left him with bile balls that night but he should know better. No means no. 
Anyway, I saw him last night and he was talking about fucking girls and shit. 
Ugh. Idk what to do. I really want to keep my friends but I know he was there first.
