i'm only 17. okay so me and my boyfriend have been having sex for about a year and 2 months he has been tested and he was negative. i have had sex 2 other times before him with a different guy but he was a virgin and so was i. i haven't been tested yet. i have a red bump on my vagina lip right beside the hole. im thinkin that i cut it when i was shaving and didn't notice. it has been there for about a week. i popped it and white stuff came out but nothing else. i put some hydrogen peroxide on it just now. could that help? what could it be?
