My bf's frustrating response to a wet dream...

I need some major advice, ladies...

My boyfriend is considered one of the hottest guys in my high school. I'm not just saying that as a proud girlfriend, but people tell me that I've "scored big time" all the time. His snapchat is basically just filled with girls who have been trying to get with him for years, so I'm used to girls being all over him. But, he's a loyal and loving guy so he'd never cheat on me.

Yesterday, though, this one girl that he knows texts him saying that she had a dream about him. She then went on to explain that the dream consisted of them having super "hot and rough" sex for two hours and that they had to take many breaks because they just kept going at it. His response to this? "I'll take that as a compliment" She then goes on to ask him more questions about his sex life like "How long do you typically last?" And "what is your favorite position?" The worst part of all of this: he doesn't explicitly tell her to stop. He just responds "I don't know" and actually answers some of the questions.

When he was telling me all of this I was shocked, not at the fact that some girl said this to him (I've heard many stories of girls having dreams about him) but because he is still talking to her and seems unphased by all of this. His response pissed me off. I stopped talking to him yesterday because I didn't understand how he didnt understand that I was upset. The way he handled it annoyed me. This specific girl has done it multiple times too and each time she says it won't happen again.

He's loyal, 100%, so I trust him. But I worry that he hasn't cut her out, or these other girls too, because he likes that type of attention. I don't want to be the type of girlfriend that tells him who he can and can't talk to...but it would make me uncomfortable if he kept doing it. But I don't know what to say to him...I can't put into words why I'm uncomfortable and what I want from him now. Is giving him the cold shoulder unnecessary? Am I overreacting? Should I confront her and tell her to leave him alone? Should I change the attention that I give him?
