I have regular unprotected sex with my girlfriend about 6 times a week, but we have not slept together for about 10 days.. and About a week a go I noticed two pin-head sized blisters on the head of my penis and then the next day they really started to itch and burn especially during urination, then I noticed that another 2 more popped up right on the base of the penis head. After about 3 days, there was pungent (like a dead rat) smell coming from that area, which totally freaked me out. Now the base of my penis burns, itches and when I pulled the foreskin down, the inner layer was red and there was a yellow pus like fluid there. I am really freaking out about because I cant go the doctor just yet because my insurance has not come through yet... and I hope someone can help before I go and visit a doctor.
