I had rough sex twice a week for the first time we used no protection and he made a mistake by doing you know what inside of me (I KNOW STUPID STUPID MISTAKE BUT I LEARNED FROM IT) and the first time it hurted soo bad and the secound time as well but it didnt hurt as bad as the first time and this happened a month ago..and just a copule days ago i noticed that the opening part of my vagiana would tingle so my friend was like well maybe you should masturbate so i did just that and it did feel better than a few days later i felt that the walls of my vagiana were swollen and it itched..do you know what could of caused this i'am so afraid of what it could be....
