Molested or night of regret?

Months ago let's call him Paul. Paul he was a friend of mine. I wasn't interested but I had these two friends who kept saying that he liked me and I should date him so I warmed up to the idea. One night I went to his dorm to watch a movie on his laptop. After the movie finishes he starts kissing my neck. If it was any other guy I'd push him off right away but I thought I was with a friend so there was some trust. Before I realized it I'm lying down and he's on top of me. He tells me "We don't have to do anything thing you don't want to, but I do want it." I got rigid, I started breathing through my mouth, and my hands and feet went numb instantly. He put his hand up my shirt and kept touching me. I spoke up. I said "My hands are numb" "maybe we shouldn't" "Why are you doing this?" "My hands are numb." I know he heard me but he didn't respond to anything except for the second time i told him my hands were numb he laughed to comfort me.

It was obvious that I was uncomfortable so he offered a back massage. It did help calm me down. I have to be honest, after the massage he went back to showering me with kisses and it felt good now. At this point it felt like Paul was worshiping me without asking for anything in return. But my hands never stopped being numb. So it felt good and bad. Paul puts his hand on the rim of my pants, I know this is wrong so I say "no" and I move his hand. He tries this a second time and again I block. The third time I grab him by the wrist and loudly say 'NO" He doesn't go for it again. It get's late so i leave. But i'm still in my good/bad feeling (an afterglow/numbness.) I just go home and sleep. In the morning I regret everything. I also learn that Paul is the kind of guy who's never been in a relationship but has had plenty of "relations" before. I thought it was a night of regret. But it's been months and I've talked to a few friends men and women my opinion is shaky now. There are two sides.

"You didn't want it at first and later you even enjoyed it. What did you expect?"
"When a person is stimulated chemicals are released in our brains that make us trust more. It's not your fault."

"He gave you a chance to be clear, if only you took advantage of it. It's not like he's violent."
"If you were uncomfortable he would've picked up on that even without words. I would've backed off right away. When you were clear it still took 3 tries."

Just know that I did not know what I was getting in to. Before this moment I was never in another intimate relationship. And the Sex-Ed from my highschool was pretty awful. Maybe I should've known these things but I didn't until my first intimate relationship with my boyfriend.

One of my big flaws is that I don't trust my own judgement. I normally do value a peer's opinion over mine. So if something goes wrong I usually immediately dismiss it as not a big deal in. I always thought that was why i had my night of regret
