Blisters on Penis

by octain, Jul 20, 2006 12:00AM
Hi, I recently developed blisters on the base of my penis. This was after over a week of a LOT of sex with the same partner. She had quite a lot of stubble as she normal shaves her pubic region, so I though that this may have been the cause of it, I also developed a very sore red penis for a day but that has cleared now leaving only the blisters left.

My GP advised me that it was HSV and sent me for a blood test, I am going to be waiting a week for the results though.

Do you think this might be the case?

I have no blisters on my head or shaft, only on the area that have a lot of friction with the pubic hair, and they are not itchy (a symptom which I’m told is common with HSV).

My guess would be that this is not herpes, but rather the results of irritation.  Keep in mind that even if it is herpes, it wouldn't be from this sexual encounter, because first-episode herpes consists of very high fever and swollen glands, not just blisters.

If this were somehow a first attack of herpes, your blood test wouldn't be positive yet, but after a week a herpes culture wouldn't be likely to be positive.  My advice therefore is to find out that the test is negative--as it's likely to be--and then to repeat the test in 3 months.

And if the test is negative, next time you get a suspicious rash, show it to a skin doctor with more expertise in herpes....

Best.

I have developed something quite similar and would like to hear your opinion.

I have developed tiny blisters that seems to have a clear liquid inside of them. There are maybe 4 or 5 of them in an area that is maybe equivalent to a centimeter or two in diameter. Another user in these forums has described it well as clear sweat bumps. The area is also itchy and obviously unpleasant. I noticed the problem a few days after rigourous masterbation (masturbation). The first time this occurred, I was tested for herpes and all tests came back negative. This was approximately 2 years ago and since then, ive only had this problem occur once (so once a year maybe - both times after rigourous sex/masterbation). Ive scrolled through these helpful forums a few times and have noticed similar comments, however, as described, my area is itchy.
Any thought? I dont htink its herpes... rather a bad irritation.. however, looking at some pictures through google, it sorta looks like herpes?
Your assitance is appreciated very much.

to add... the first episode did not come with any flu like symptoms or headaches or anything else that accompanies herpes for the first time - hence i was not surprised to learn the first time that my results were negative.

Thanks again Doc.
