Hi, this is so embarrassing. I m 18, I ve been sexually active for about a year. I ve been with one guy and nobody else, so thus I know I don t have a sexually transmitted disease. I am also 100% sure he hasn t cheated, and I m not being niave. There s a lump underneath my vaginal opening, it hurts to press and when his dick enters me. Attatached to this there s a hard painful little bit. There are a few spots on the skin around but they re shaving pimples I presume as I shave all over. I feel or looks disgusting down there and I don t know what to do. Thanks!
