For your sexy Saturday night, why don’t you share with your partner the first time(s) you masturbated. What did you used to fantasize about, how often did you do it when you started, did you think it was wrong to be doing it.
It leads to some fun and interesting discoveries about your partner. For instance, I learned that my wife started masturbating relatively late (while in university) but had an intense summer where she seemed to do it almost constantly. I, on the other hand, started younger but without the intense ferocity of others my age.
