i have talked to a few of my friends that are chicks about masturbating...they all said they have never masturbated, they said masturbating is not a big "turn on" for them and they said that their "genitalia" grosses them out. and i am pretty sure they were tellin the truth cuz one of the chicks was my gf and i tell her all my masturbating stories...lol...so are most 15 year old girls not interested in it...untill they get older or wat
my g/f when we were 17 claimed never to masterbate. Later, as adults, she confessed that of course she did.
i had started masterbating before 15, i wouldnt have admitted that to a group of people. i'm open about my sexuality but not to the point where i would have talked about it at that age.
