ok i am 16 and am sexually active. Although i have not had sex in 5 months, last night my vagina started itching like in between like where the vaginal opening is.... well now my clitorus and labis is swollen really bad.... My mom came on here last night trying to figure out something and read thast 1% cortosone works .... well i tried it and it helped a little bit but after a while the swelling gets a little worse.... Could this be an STD?? I am very scared and would appreciate any help... Please help...!! Thank you!
