I thought it was quite obvious that my answer was a joke, seems it wasn't clear enough . Obviously a normal person would kneel and ask her to stop. (I hope this one is more obvious XD). In a more serious tone... just tell her to leave you alone on those things, there are many others that could be the "human experiment" that she needs. However personally I would play a trap game if it doesn't have sex scenes.
I see. don't worries bro. maybe you just don't wanna betray that feeling of yours. your mind try to give you some leeway. if the girl that you like already married, you better find someone new.
