Im 21 years old and about a week ago me and my boyfriend had unprotected sex for the first time(both virgins) for about a week and maybe twice a day, about a day or two later I ve notice a cottage cheese looking thing around the outside my vagina and it s alittle itchy..don t know if it s an infection because when I pee it doesn t hurt or smells bad..so I just want to know if u guys have any clue what it is and If it is an infection what medicine should I use to get rid of it. Thanks!
