I am 17 and am sexually active. My boyfriend and I have refrained from sex for the last six months or so. We have done other things. He rubs my clit while I give him a hand job. We have been doing this for about 6 weeks almost everyday. Now I have a split in my skin on my hood. Its as if I have a cut. It is very painful. What is it exactly? What do I need to do co it will go away? and What do I have to change to make sure it doesnt come back?
