hey, i am 16 and have always been horny since i was late 14 but i never knew how to ‘jerk off’ or cum. ive tried many times before, the up and down motions, its never felt as good as if i were to rub it against my bed. obviously all dick sizes are different and depending on the size people masturbate differently. i wont share this information yet but from reading online i think mine is about over average. if anyone can reach out and give tips it would be very helpful, dms open until i learn how
