guy pushing your head down when sucking dick?

Em
Ok or not ok?
I slept with a new guy last night we've been talking for about a month a he seemed quite sweet
Did not expect him to be pushing my head down when sucking his dick or asking to cum in my mouth
There was also a moment where I wanted to change positions cos it hurt and he said he was gonna come soon and keept going
Feeling quite violated now I look back 
Just wondering if people would regard these things as normal or too far considering I didn't object 
Not tryna accuse of anything just tryna figure out if I should stop talking to his ass over it
