Touching a woman's nipples is only the first part of a sex scene. It's torture, and you have to work your way through the nipple until you get to the point where you're "tormenting" the woman. Touching her pants is the first step in this torture. You have to "grind" and "pinch" her until she's "slump pant dazed" . You know, the kind of thing you'd do if you were in the middle of a rape scene, but you don't have to do it in front of a bunch of other people. You can do it behind the scenes, too, but it's not nearly as sexy as it sounds.
