Me and my partner were having sex last night he was very interested in my clitoris after awhile he got rougher while we were having sex it wasent painful but afterwards while I was going to wee and I noticed a stinging pain I never felt before I nearly cried it was so sore after I checked myself down below I noticed one side of my clitoris was very swollen and red only on one side since then the pain has eased slightly but still very sore can anybody tell me what it is as I'm very worried it was unprotected sex also we had but I have the implanon bar
