so... my boyfriend always wants to do me a handjob for me to come, but he just doesn't get it ahh! its kinda hard for me to explain him because by myself i just start by toching my clit to get me in the mood, but for actually getting somewhere i need to do movements with my hips to a towel or pillow or something i'm able to manipulate in order to ,"rasp" my clit, not with my hands. i've never actually been able to have an orgasm only by toching my clitoris, is this normal? does anyone else has the same process?
