On December 10, I had sex with a stripper. She pulled out a condom and placed it on me. The sex didn't last long. The next day my penis felt strange, kinda like what it would feel like if air was blowing on it. It's not very itchy, It hasn't burned going pee, but I have a feeling that could have genital herpes coming on. The skin on my genital region feels tender and walking around is slightly uncomfortable. Today is the 4th day since possible exposure to HSV 2 and the feeling has gone down slightly but still there. So far I haven't had any bumps, scars, or sores in my genital area. I read that low back pain and slight pain in the left could be a symptom. I do have slight low back pain that comes and goes and my left knee aches slightly, but I do have a history of low back pain so I'm not sure. I haven't been able to eat as much recently either and went I try to my stomach gets upset. I know it's probably too early to tell or that my anxiety on the matter might be causing these symptoms but I just would like someone else's take on the situation. I'm 20 years old and made a stupid mistake and I'm also wondering if and when I should be tested for stds.
