(Girls)Why is my Vagina bleeding?

Okay my vagina is bleeding.I have never had sex.I never finger myself.I do masturbate,but I just rub.It never hurts .I noticed it was bleeding when I went to the bathroom and put put toilet paper down there to clean myself and then i noticed it was red and was blood.Am I going to far when I clean myself down there,or is something wrong with me,or am I just on my period?If this helps,I was wearing skinny jeans the whole day (almost didn't fit me and left stretch marks on my waist.)I've never had my period,and It doesn't hurt to pee.I tend to touch myself down there sometimes,because Im wet down there often.Please answer I'm getting a little worried.
