Don't freak, it's too hard on your nerves. When I figured out my wife had been cheating, I got real nervous, and to top it off I have a mild "problem" once in awhile that is yet undiagnosed. Not long after my wife took off, it flared up and I went to the doc and got checked out. I was severely freaked. This may help you get an idea of what you will be dealing with, and is also posted for the benefit of those who may be ignorant of reality here. Anything I screw up, Dr. Jarhead please correct me. Also, feel free to add anything you feel is appropriate.
Herpes can be caused by two strains of the virus, HSV-1 and HSV-2. HSV-1 is most commonly found as cold sores. HSV-2 is the more common virus in genital herpes, but HSV-1 will cause it too, and the most common cause of HPV-1 genital herpes is oral sex. There isn't a guy in the world that will turn down a blow job right? Well, all kinds of chicks have HSV-1 cold sores, and furthermore, you can shed virus without even having sores. No kidding, this stuff is more common than you might think, and anyone who just goes "eeewwwwww" isn't up to speed with reality. Estimates run as a high as 25% of all women have genital herpes, either HPV-1 or 2, and many of them are asymptomatic, which means they never get external sores. That's one in four women! It's not limited to any particular demographic either! This means that if you have sex on more than an occasional basis with someone who is not a life partner, and have not gotten anything, you are just plain damn lucky!
I went and got checked out. Swab/culture test was a little bit late but my Doc was pretty confident that if there was something there he got it. He also felt it was going to come back positive. The test came back negative. Did a blood test called a Pockit test for HPV-2, you get the results while you wait. Negative. Did HIV, Hep B and C, etc. These tests get sent out and take a week or 10 days. Negative. As far as the second and more painful swab test, he gave me the option of that or a big dose of Cipro. After describing the test....I took the Cipro instead!
Here is the kicker. I was married five years and my wife never got pregnant. I met with her after we seperated for good and I told her that she needed to get checked out because at that time my Doc felt that there was a good chance that swab test was going to show something. Two months later, she is pregnant. That tells me she had something, most likely Chlamydia, a mild bacterial infection that is the most common STD out there. One of it's consequences is temporary sterility. I imagine she had it the whole time and I had it too.
Moral: life is hard. Even if you're NOT stupid....I am actually pretty bright. And STD's are much more common than people realize.
