Honestly, I don't mind sex. I don't mind it in things like Game of Thrones, or the setting in general. It happened. It's only certain closed minded groups that shun it. It makes perfect sense for it to be part and parcel for any fantasy setting, ever.
A game that was only made for that content though, are routinely terrible.
The comproise, however, would be a check box in the launcher* as I am personally not bothered by it... but it is DnD and it does cover all age groups. Child locking, proofing etc, should be a choice for any parent buying for someone under the M rating. Shouldn't be buying EA games for kids anyway, game isn't done. That's when nudity tends to sneak in and other bugs (even for games not M rating).
