Which leads me to believe the only reason he came on the show is for fame/popularity.
I mean, I can't see Maura getting a shag off him on the outside either?
Exactly this.
Tbh I think most of not all of them are on the show for fame/popularity. It could be that Curtis doesn’t want to sleep with people because in his own mind that is taking it too far? He will play the game and then stop. Maybe he doesn’t believe in casual sex/intercourse unless he has real feelings and he won’t go there. The problem is that can be interpreted the wrong way when he is seemingly happy to go so far.
Some of the others are ok with casual sex.
I believe Curtis is playing a game but is pretending to use his moral compass as his get out clause and that is what is causing the confusion for both Amy and Maura. He is using them and as the consequence is deliberate hurt, ultimately he isn’t any better than Jordan, Michael, Tom etc You could argue he is just playing the game where the goal is to stay in as long as possible. As frustrating as Alex was last year, I don’t think he set out to hurt anyone. Maybe Curtis is similar except he is leading the girls on which is something Alex didn’t tend to do.
