Sex in video games is an odd thing. For instance, Kratos is allowed to off-screen bang Aphrodite so hard and well in God of War III that her handmaids are overcome by lust and start going to town on each other. You even get rewards for executing this scene correctly. Yet, for a long time sex in games was a big no-no, as they were seen as a children's toy only, and even today it's still pretty scarce. Some designers managed to slip in some cheeky smut every now and then.
Sigh... Just to get it out of the way, Grand Theft Auto: San Adreas had a sex minigame built in that was ultimately cut. However, because some of the animations were used elsewhere, they couldn't just delete it without screwing up another part of the game. The answer was to just make it inaccessible, but a download patch re-enabled the minigame resulting in lawsuits, recalls, and a puritanical brouhaha. Literally the next year, Kratos began his regular sex conquests openly, so who the hell knows why the world went so insane over this?
