nothing just going with what you said. you know your body and thats how most ppl go about. girls that dont know their body obviously suck in bed. you need to know what it takes to get off and pass it on to the partner so they can get you to your point if they arent sure of thier partners
unexperienced partners suck for a good bit of time untill you teach them, if they cant be thought then might just have to let them go
