get some biting into the action, sorry if this is awkward, but what really turns me on is when my boyfriend bites me or he would jerk at me and make me pay attention, kind of like cat and mouse, possibly if you both are open to it there's always the possibility of getting toys into the equation.
i know what you mean by your question too because its happened to me.. but yea just do things that you and your boyfriend will be new too

HAVE FUN!! Lil
