Hi im a 19 year old girl and have been sexually active for nearly four years now. Over the past several months i have notice something strange in the opening of my vagina. It looks like a four leaf clover shape skin tag which covers up the whole entrance, but it has stopped me from havin sex with my boyfriend as it is very painful and when he is trying to enter i have to stop him because it is so painful. This pain can occur when we are in foreplay but does not hurt when inserting tampons. Anyone help me out here please :(
