Hi, I just recently had sex for the first time in about a 2 months. During intercourse, I started feeling tight pain in my vagina and I just thought it was because I havent had sex in awhile, so we continued. At work that night, it gave me discomfort to walk and it was painful to the touch. I got home about 5 hours later and discovered about a quarter size dark bruise on my left side of my labia majora and slight bruising going all the way up that side until where my pubic hair stops. Its very swollen and very sensitive to the touch only on my left side. This has never happened to me before and Im worried.
