I have no typical symptoms to speak of, no discharge (that I’ve noticed). Only minor pelvic pain, and strangely thick, clumpy semen. 

I was tested for   Chlamydia and Gonorrhea and Trich at 1 week, again at 17 days including myco and ureaplasma this time, and blood tested at 1 month. I was negative for everything except HSV 1 which I’ve had since a kid.

Am I in the clear? I am concerned about my thick semen. I’ve seen that hormonal imbalances can cause this phenomenon and I’ve certainly been extremely anxious. Thank you so much in advance for you help 

Oral sex became much more frequent over the past few decades in comparison to past years, in part because it is a lot safer than vaginal or anal sex from the standpoint of HIV and other STIs (and of course zero risk for pregnancy). The infection risk is low enough that oral sex can be considered safe sex -- with near zero risk for some infections, including HIV and chlamydia, and low risk for all others. Despite this inherent safety, in more recent years people have become more concerned than necessary about the infection risks.

The low risk is both because oral STIs are uncommon, so usually there is no infection to be transmitted; and even when STIs are present, they are not easily transmitted by oral sex. Assuming your co-worker is not at especially high risk your chance of any infection from this single event is less than one chance in several thousand -- especially with such a brief exposure. If you had asked about testing before doing it, I would have recommended against any STI testing at all. And some of your tests made no sense. Trichonmonas, mycoplasmas and ureaplasma are never present in the oral cavity, therefore not possible from oral sex. Your negative gonorrhea/chlamydia test result was conclusive. You also didn't need syphilis or HIV blood tests, but those results show you were not infected.

No STI causes "thick semen".

All is well; you were at little or no risk and didn't need testing at all, but your test results mean you are in the clear. All is well.

I hope these comments are helpful. Let me know if anything isn't clear.

Just a couple quick follow ups. 

1. My semen being extremely thick, jelly like ; what could be a cause of that? Stress? Prostatitis? Stress induced prostatitis? 

2. Stress/guilt/shame induced symptoms seem to be a high frequency occurrence in these forums. Is it really just us looking for symptoms that aren’t there? 

3. Am I correct In assuming I have no risk genital HSV1 because I already had it orally? Also NGUs have been a concern, how warranted are these concerns? 

I’m now over 6 weeks since “exposure” and just ready for my body and mind to go back to normal

People are entirely immune to new infractions anywhere on the body with the HSV type they already have. And in any case, thick semen also isn't a possible herpes symptom.

I’ll consult with a urologist regarding my issues now that I’m certain they’re not STI related.

Trust me, there’s been more than enough psyche searching going on to dissuade myself from stepping out of line like this again.  

Since I’ve got one more reply, how similar are all the testing services? I’ve used one from an urgent care and one from stdcheck dot com, I’m sure you can’t recommend one over the other, but is one type of testing service generally more reliable than another? 

Thanks again
