Well, the comics that this series is tied to are loaded with sex scenes, so it wouldn't be out of the ordinary.
Buuuuuuut.... I hope not. Call me a prude or whatever, but I don't like sex in my video games. I have yet to see one game where it's handled maturely and not as fanservice. Even then, I'd be uncomfortable with it.
I'm fine with characters having sex. It's part of being a life form, but I just don't need to watch it, or hear it, or anything. Have it off screen, cut to the next morning and I can deal.
