I had unprotected sex with a girl about 8 months ago now and right after I noticed that my penis and scrotum were a darker color ( almost brown ) and I had a blue balls feeling mainly in my left testicle that was prominent for a good 4 months. I then developed a a line of red bumps on my thigh two days after the sex that went away in a few days. Then I noticed my scrotum turned red and itched quite a bit. I developed a rash feeling under the skin between my scrotum and thighs but mainly on the left side. It tingles a little but when I move it it goes away. I also had a little pain in my penis from time to time. The weirdest part is that I can't really see that anything is wrong from the outside except that its all a little discolored still. There is also on and off tingling /itching mainly around the scrotum but sometimes all over. I havn't had a moment where I felt normal down there in the last 8 months. Please help. I'm only 19
