I have been very paranoid about STD contraction lately, especially herpes. I have been checking myself constantly and I haven't found anything but this morning I found what seems to be slight swelling and redness in the area around my urethra. There isn't any pain, just slight irritation when it rubs on my underwear. To be honest I'm not sure if it looks like that all the time and I haven't noticed. There isn't any clearly defined sore and I haven't had any other herpes symptoms so what does everyone think. I'm going to the doctor on Thursday but does this sound like a concern.
