i was with my bf for seven months, and we did have sex every month&¬hing was unusual. after we broke up he had sex with another girl&&i had sex with another guy. i had sex with him a week after he had sex with the other girl&&the day before i had sex with the other guy. i noticed the other guy had something similar to a ring worm on his penis. around a week after i had sex i noticed tiny cuts,that looked like paper cuts from my clitoritis to my rectum. my vagina was very swollen, red,&&itchy. it also burned when i urinated. i started taking cephalexin which is an antibiotic, for an injury that i currently had&&the cuts,swelling,itching,burning,&&inflammation went away for the week that i took them. i forgot to take them for a week&&i had sex&&a couple days after that everything came back. i currently have these cuts,which are very painful. my vagina is still itchy&&im now experiencing white discharge that has an odor. im only 15&&im scared i think it could possibly be an std or a yeast infection. can someone please help me.
