Sex in games should really only exist either in a vaguely implied moment of amusement, such as visiting a brothel in arcanum and blacking out, waking up with no energy left, which serves no purpose other than to be a random gimmick.
Or when character interactions are kind of at a point of closeness and intimacy that it would be kind of weird for that to just never happen, even then it's not really like you need to see it happen, you get the idea, I thought Mass Effect's version of it was fine personally, and MGS3's implication was fine for what it was too.
