I’ve noticed some red marks on the end of my penis. They dry up and become scabby after a while...what could they be?

I’ve been having unprotected sex with an ex-girlfriend. Since then, I have developed red marks on the end of my penis which dry up and become scabby after a while. They have been there for a month now, and I show no sign of breaking out of the spot-scab-spot cycle. Recently, one also appeared on my scrotum. I also have experienced severe itching and an intense, prickly rash. This began on my penis (it felt sort of 'inside') but has since spread to cover various areas of my whole body...small, hardly visible dots on my hands, arms, buttocks, etc. My ex had contact with another man who apparently had the same itchiness. Any idea what I might have? Are the two things (the blistering and the rash) related? Please help!

I have a rash-like wound on the top part of my penis...what could it be?

I am 30-years-old and I have been suffering for the last three months from a painful wound on my penis. It looks like a skin rash right below the top part of the penis. If I am not sexually active, the pain and the wound disappear. But when I’m back to any sexual activity, there it comes is again: burning, very slightly bleeding and eventually getting swollen. I have tried an hydrocortisone cream before but is just made it worse. Do you think is a kind of fungus? What can I do about it?

My girlfriend gets a rash after sex. Is she allergic to my ejaculate?

On a few occasions when I get some ejaculate on my girlfriend’s thighs or after intercourse, she gets a red rash like poison ivy. It doesn’t happen right away, but overnight and it goes away after a couple of days. Is it something in my diet? Medications? Or is she simply allergic to my ejaculate? The only allergy she knows she has is to sulfites...does my ejaculate contain them? We are both 24 years old, healthy, STD-free students, and we’ve been together four years.
