I must be completely desensitized to sexual innuendo and suggestions at this point because I barely noticed. I mean, I know it's there but it barely registers in my brain.
Besides, if this game does end up having a lot of sex in it, I have faith in this team to be able to do sex the right way. I mean, with the Persona games they usually tackle a lot of deep emotional issues and they do it really well, and really eloquently. When you are writing a bunch of Japanese High Schoolers, you don't really get to tackle the issues that sexuality brings up in a lot of depth, because well, they are in High School.
All I'm saying is I don't think there is going to be sex in this game for sheer fanservice.
