Thank you very much for your time and precious help.

About 5 days ago I had a sexual encounter with a CSW met in a bar. We had protected intercourse with condom, but before she performed to me a fellatio without condom.

What are the risks? I read from your forums that oral sex can practically be considered as safe sex.

Anyway, I have been anxious about it, and today I developed redness and itchiness on my glans; I had my doctor visit me: she told me I have a mild balanitis and prescribed me an anti-mycoses  cream to be locally applied for 10 days.

Do you think I should further worry or after the cream I can move one?

A big thank you!

You are right, that oral sex is very safe -- not completely free of risk for STDs, but low risk for all STDs and virtually zero for some.

Uncirumcised men get yeast (mycotic) balanitis from time to time, so that probably had nothing to do with the oral sex exposure a few days earlier. Or perhaps some nonspecific inflammation related to the oral exposure, but not likely an STD. The main STDs of risk from receiving oral sex are gonorrhea, herpes due to HSV1, and nongonococcal urethritis (NGU), which sometimes may result from exposure to entirely normal oral bacteria. But all these are unlikely after any single exposure. Chlamydia, herpes due to HSV2, HPV, and syphilis all are rare in this situation, and none of these is a likely cause of the sort of irritation (or balanitis) you are experiencing.

For those reasons, in general STD testing isn't recommended after any single oral sex event. However, the risks are not zero, and you could be tested if you would like the additional reassurance it might offer. If so, I would recommend a urine test for gonorrhea and chlamydia and, after 6 weeks, blood tests for syphilis and HIV.

I hope this information is helpful. Let me know if anything isn't clear.

Regarding this balanitis (in my case: overall redness and burning sensation, on the glans and on the inner foreskin, giving almost a "tight" sensation; no bumps or blisters; visited by my doctor yesterday and prescribed anti-mycosis cream; today is the 6th day after the fellatio) you exclude it could be the sign of HSV, right?

I feel after 24h of the first application of the anti-mycosis cream it is slightly improving.

Please help me because I am very anxious about He possibility it could be HSV.

Thank you very much!

I really don't think you need to be worried about herpes. But of course return to your doctor if your symptoms worsen, if open sores develop, etc.

I am very very anxious about it; may I sum up your thinking as it follows to help me rationalise my fears:

- Oral sex is very safe;

- Oral to genital HSV through a single exposure  is unlikely;

- Oral HSV is the HSV 1 type, which is less worrisome than HSV 2;

- My symptoms do not sound at all like herpes, especially because of the lack of blisters and sores (I keep checking), that should have already appeared.

- If ever my symptoms worsen I should go visit my doctor, otherwise I should calm down.

- HSV test is not recommended.

Thank you very much for your great support!

That completes the two follow-up coments and replies included with each question and so ends this thread. I hope the discussion has been helpful.
