I'm really glad you brough sex scenes into it because it actually perfectly fits together.

A lot of movies have a lot of unnecessary sex scenes of which the only use is pleasing the audience. The sex scenes show unrealistic representations of sex. Now in some movies like Superbad the sex scenes are not only important for the plot and character arc but also not glorified. Not all gay people are amazing and not al sex is amazing. You can say that a certain character has had sex before but don't unneccessarily make a big deal about it.
