It is also not just about sex there are other thing going on in the game.
Sophia will have sex with a guy but she will have sex with people she can trust and knows,why ruin her marriage because she still loves Liam,
So if you expect a gang bang wit the students,Aiden gang or even the Logan idiots then you could be out of luck.
