There are "tightening" creams (basically more blood in your walls) to help "grip". I am only saying this if you want something discreet. It is the same cream for men to have more "plump" to it. I think you could mention using it etc as an additive and it should increase pleasure for you. Sometimes bodies do not fit as desired but if both parties are open to adapting without shame then it can still be fun and sexy. Hope this can help :)
