I'm 14 and haven't been masturbating for that long. I usually use my finger or a long marker but cannot cum. I need help figuring it how to cum.
I recommend watching something erotic then rubbing the clitoris, this may take awhile but trust me, it's worth it!
I wouldnt worry too much i was with my 1st boyfriend for 3 years and never came once even though id had orgasms, just nothing was coming out... most girls don't come till they're about 17.
