Hello, I am a white 37 year old male. About 12 days ago I had an incident where a male masseuse put my penis in his mouth, this lasted for maybe a second or two and I pulled it out and explained I didn't want to do that. It maybe went in his mouth a couple of inches, as I was completely flaccid and not erect. Also, he briefly grabbed my testicles and penis prior, but only for a moment. It happened very fast and was over equally as fast. The massage finished up 10 minutes later (a very awkward and silent 10 minutes) and then I went straight home to the shower and scrubbed myself. 

Welcome to the forum. I'm happy to help.---

Thank you so much for your reply!  This is the answer that I anticipated but wanted to ask regardless. Having said that, I'd like to follow up with some updates. I went ahead and was screened at the health clinic regardless, as you said I would.  I did do this before your reply but would have afterwards anyway, just as you said.  Anxiety is a hell of a thing...  Secondly, my penis is definitely more sensitive right now, I'm not imagining this.  During manual stimulation, I noticed that there is some sensitivity increase. There is a slight menthol-like sensation coming from my groin and anal region (no sexual activity occurred there). When I ejaculated, it felt normal at first but then had a slight burning feeling once completed.  Given this information, does that change your opinion or is it possible that I have gave myself anxiety induced prostatitis?  

I'm sure you're not imagining your increased penile sensitivity. But that doesn't mean it isn't anxiety related. The anxiety effect definitely increases pain, discomfort, and so on; I'm not saying your symptoms are "in your head", for example. In any case, there is no STI that possibly can cause such a symptom.---

Thank you Dr. Handsfield!  You'll be happy to know that the gonorrhea and Chlamydia screens came back negative. My WBC is normal (even slightly lower than 2 weeks ago when I was tested for something else unrelated).  Having said that, I'd like to ask one final question, since this is my last reply.  I still feel a slight burning sensation after ejaculation, but briefly and not intense. Also the tip and surrounding skin are still somewhat sensitive - sometimes I believe I feel a pinching sensation up there. And, I feel there may be some urethra irritation as well as minor itching/tingling around the genitals. Everything is mild, not severe and there is still no discharge, pustules, or lesions. Is it possible that there is a trichomoniasis infection?  Outside of the aforementioned encounter, I've never had penetrative sex with anyone other than my wife in 14 years.  Other than trichomoniasis, can HSV mimic these symptoms.  I appreciate your time and your help in alleviating my anxieties. As this is my last response, I will say thank you for your help, no matter how you reply. Best wishes!! 

No STI causes the sorts of symptoms you describe this time, including herpes. You name the actual symptoms of concern ("discharge, pustules, or lesions"). As before, these symptoms are most consistent with increased awareness of unimportant sensations on account of your worries about the situation. Please accept all I have said and move on without further worry. You can safely continue sex with your wife without any risk of any infection on account of your massage experiences a couple of weeks ago.---
