Maybe you got that from the 'forced' part of the OP. The game already pulls 'death/rape' pics when a customer does that to her in the summary. It would also be called up if player choices were also based on the pics in the categories used for summary/type of sex pics.
If you don't like the 'death/rape' category (not a big focus for most girl devs btw, probably the 2nd most unused category, the 1st being preg), do as you have already done, and remove the pics you dislike, and if this was to become a feature, just don't rape your girls. both problems taken care of lol.
Still, wouldn't you find it neat for normal sex acts to call on the 'sex' category within your interactions? Or whatever act you'd like to see? Not really that important, but handy nonetheless.
