[Question #7639] Yeast infection

13 days ago
Hello Doctor, sorry for my bad English. I am a man 47 y.o. Circumcised living in Tokyo. Last January I had an intercourses with a Japanese escort (protected vaginal sex and she gave me unprotected oral) I only met the woman once a month and she test herself twice a month. After 3 weeks from exposure and noticed an inflammation on glans, like a red  rash not painful. An STI doctor by scraping the skin and examination by microscope told me: yeast infection (balanitis?), and gave me an antifungal creme for 2 weeks. He also said I can have sexual intercourse. Here is the question: the rash it’s still red, I better use condom? about oral sex, can a woman perform to me or I can infect her? I searched on this Forum and learn that yeast infection aren’t STI. Is it true?

Welcome to the forum and thank you for your confidence in our services. Unfortunately, however, I really can't help very much.

Balanitis (inflammation under the foreskin) is common in uncircumcised men, and often is due to yeast -- but it's not an STI. You probably did not catch it from your sex partner:  yeasts are entirely normal under the foreskin and on the skin of the genital area. When yeast causes symptoms, it usually is not because it was caught from a sex partner. That's why your doctor advised it is OK to have sex:  you have nothing that will harm a partner. Should you use a condom to present further irritation? That might be a good idea, but only for comfort, not for disease prevention. The smart thing is to avoid all sex, either oral or vaginal (with or without a condom) until your penis is back to normal. But this forum only deals with STIs, so this is outside our expertise.

Im sorry I can't be more helpful, but I hope this information is useful. Let me know if anything isn't clear.

Hello Doctor, thank you for fast reply. I understand about 90% of your answer, I summarize here:

1- I dont' have a STI
2- I can have sex with a partner without risk of harm her 
3- To avoid further irritation better avoid sex until full recovery
is it correct?
Jut one last question: I have a plan to meet a sexual partner next week but I never use condom with her during oral sex (vaginal sex always protected).
Could she get infected by yeast infection in her mouth, performing fellatio to me? thank you very much.

Yes, you correctly understand. 

By the time you meet your partner, apparently you will have been using the antifungal cream for a week or more. Even if irritation persists, the yeast itsaelf probably will be gone. Oral sex will be safe for your partner.

Thank for the answer! Last question and the n it’s time to move out. I started the creme Friday evening, and from red it’s now pink, so it’s healing pretty good. For the piece of mind, should I use a condom during oral sex ( as you understand I am worry for her) or is not necessary? Thanks for the patience!

I've told you all I can about condom use or not. I'm not an expert in this area, but I see no her with or without a condom. But I suggest you discuss it with the your partner. Shouldn't it be mostly her choice, given your uncertainty?

That completes the two follow-up exchanges included with each question and so ends this thread. I hope the discussion has been helpful. Best wishes and stay safe.
