Even lower risk with such a brief exposure. Don't worry about it.
Hello Doctor and thank you very much for the fast reply.I feel much better after your comment.so the only risk was the unprotected fellatio right?That happened just for a brief moment, maybe less than 10 seconds.It change something, long or short (in terms of time)exposure?
Thank you!
Welcome to the forum. Your English is OK.
Condoms work well to prevent most STDs; the vaginal sex exposure carried no significant risk. Cunnlingus (oral-vaginal contact) is extremely low risk, even without protection. It is very unlikely you caught any oral STD.
Unprotected fellatio (oral-penile) is low risk for the penile partner for all STDs and zero risk for some. It is uncommon to be infected after a single exposure, but there is a small chance of gonorrhea, herpes due to HSV-1, and nongonococcal urethritis (NGU). Syphilis is theoretically possible, but heterosexually transmitted syphilis is rare in Japan, so extremely unlikely. There is no risk of HIV, HSV-2, or viral hepatitis, and little risk of HPV.
If I were in your situation, I would not get tested and I would continue unprotected sex with my wife. You could add still more safety by waiting 2 weeks to have sex at home; if no symptoms (urethral discharge, penile blisters or sores), then go ahead. I see no need for blood tests. Of course if any symptoms appear, see your doctor or a clinic.
I hope this has helped. Best wishes-- HHH, MD
