koikatsu gives a variety of different poses and a speed controls that adds extra poses. It allows the use of hand / finger / tongue and later toys once acquired to be used on different parts of the body. Remember though that depending on how you or others design the character they may not allow certain types of sex until they have been leveled up i.e. some won't allow anal touching or sex and some will insist you use a condom. (cheats can usually counter this)
Using hand / finger / tongue and later toys once acquired on different body parts will "level up" those areas and give more points for first time interactions.
At the moment, outside of touching games, illusion has the best games of these types and also the most stable. Plus the modding community is very active with them compared to other game of the type.
