I don t know if this is normal but it really freaks me out , I rarely masturbate, just sometimes in the mood.(once a week or once every two weeks) I noticed when I do(I don t put my fingers inside, I rub my clit until orgasm), I bleed A LOT, right afterwards. I m on a depo shot so I do not get my period, I ve had sex before, just to mention that in case it could be of any use. I spot sometimes, but not as much. I have to wipe many times to get most the blood gone, but hours later or even a day there is still trace of the blood from the day before.
