I am a 17 year old female. I have been sexually active with one guy within the past 4 months which is the only guy I've done anything with who is not a virgin. all of our intercourses have been unprotected and I am currently on bc to regulate my menstrual cycles. my parents do not know I've been sexually active neither does my physician because i don't want my parents to know. I have been on my cycle this past week and my boyfriend and I decided to try it during this time a few days ago. I had to stop early because it began to burn around the lining of the opening of my vagina. we tried again 2 days later and it hurt again. the next day I tried one last time and after a couple thrusts, I quit. between my anus and the opening of my vagina is extremely sore and with a mirror I saw a line lookin bump,-very small- that is a red color that hurts to wipe and sometimes even sit. along with it is an odor that does not smell very great at all. it also may cause spotting a little at times and burn to urinate a tad. what might it be and what can I do? id rather not go to my doctor since my boyfriend and I both would probably be in extreme trouble by our parents who are over protective and strongly religious.
