Hello and welcome to HCM. Thank you for your query. Based on your description and your sexually active status, it does sound like a sexually transmitted infection, which has resulted in a genital wart. Usually caused by either HPV (human papillomavirus) or genital herpes. Of course, we cannot confirm this without physical examination or laboratory investigations, which is why I would advise you to visit a doctor and get diagnosed at the earliest. In the meantime, please discuss your partners status as well, and request him to get screened. Also, it is very important that you abstain from sexual intercourse till your are diagnosed, treated and infection free. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you. Best wishes.
