Sexually Transmitted Diseases/Bubble at tip of penis



I've had a bubble at the tip of my penis for as long as I can remember.  It's clear, almost feels like theres a fluid in there.  It doesn't hurt or bother me, it just makes urinating difficult.  I've never had sex before and I just don't know how or why it is there.  I thought maybe it could have appeared because I'd been hit with a ball or something like that a while back.  I was just wondering if there was anything I could do or am i in some type of danger as I fear it may be an std.  what would be the best course of action.

Thanks in advance

Hello James,
If you have never had sex with anyone, than it couldn't be a sexually transmitted infection, which really requires sex with an infected person. Sex means any naked skin to skin contact involving your mouth, penis or anus with another person's mouth or genitals or other body parts.

Also, any type of infection, including most STDs, cause sufficient tissue inflammation so that you have some recognizable signs or symptoms (redness, swelling, rash, itching, pain, bump, etc.) that progresses or regresses, but usually does not persist in the same form. A consistent blister like defect initially sounds like the virus herpes, but this requires prior infection. Since you may have traumatized the area in some manner, the more likely possibility is a friction blister or cystic structure or some other normal variation in the skin that you may be unfamiliar with.  

The best course of action is to either have a doctor examine you, or see if a period of time makes it go away by itself.

Good luck!

Almost any question or concern about gay men's health issues, sexually transmitted infections, abnormal Pap smears, anal cytology (anal "Pap smears"), etc. There is no such thing as “d/d free” or “clean” (free of infection), so why do so many of us deceive ourselves into thinking that some people are indeed totally free from a potentially infectious disease, like HIV, herpes, hepatitis, syphilis, chlamydia, warts, gonorrhea, etc., just because they say so? Clinical laboratory tests are not perfect, and having a “negative” or “nonreactive” test does not mean that a person is free from infection. Perhaps at the moment the test was taken, the person was uninfected; or, perhaps, the test wasn’t sensitive enough to detect presence of the infection. There is really no way that anyone can determine that they are truly “disease free,” and there are over a hundred of infectious conditions that can be spread without your knowing anything. Rather than trying to “pre-screen” or “serosort” a potential sex-mate with deceptive questions that are impossible to know by today’s technologies, a wiser option may be to consider everyone infected with something, and either use appropriate protective measures (“safer sex”), or accept the responsibility and consequences of possibly “catching” something from someone who’s hotter than expected (pun intended!). There is much research that supports the contention that an HIV positive person reliably taking HIV medications, and having an undetectable viral load, presents a lower risk for transmission of HIV than people who may think or say they are HIV negative, but are not. Food for thought!
