Hello, I have recently got this iching feeling on my penis and on my thighs. I am 18 years old. I had sex about two weeks ago on the beach, in the back of a truck. Ever since that next day i have been inching on my butt, thighs, and genital area. I used a condom when we had sex. Also i had a sore throat for a couple days. I recently noticed like 3 days ago these little red itching spots on the tip of my penis. They are not blisters or open sores, but they do seam to itch more at night. Maybe thats because i have nothing else to do but think about it. Also I have received what seams like a cold now, runny nose, headache, but i don't think a fever. Im not sure if that is related to the itching but anyway. Could this be an STD? If so what kind? What other kind of problem could it be if it wasn't an STD?
