Ah -- I see that my statement was ambiguous Sorry.
"That" refers to the 1 in 100 risk; i.e. the risk is a lot lower than 1 in 100 in heterosexual oral sex.
B is supposed to say "no more than one in a hundred".
A) Oral herpes could be acquired by genital contact or, more commonly, by kissing. However, the initial oral herpes outbreak typically causes multiple painful sores and severe sore throat. So I doubt your oral sore is herpes.
B) My guess is that no more than one oral-genital exposure (among two men) results in STD transmisison. It's a lot lower than that for heterosexual men and women.
It probably is safe to have sex with your wife, but I cannot guarantee it. The chance you infected is very low but not zero. For maximum safety, visit a doctor or clinic. Your local health department STD clinic (or its equivalent if you in a country other than the US) would be an excellent choice.
Thanks doctor. A few quick follow up questions ifmyou don't mind:
a) I have developed a small sore on inside of lip. Feels like a sore when you bite your lip but I don't remember doing so. My exposure was 5 days ago so I am wondering if this is the first sign of herpes. Can genital herpes transfer to mouth? If this sore cleared up in a few days, is that a sign it isn't herpes? How long does it normally last? What are major signs?
B) how often does oral sex result in some form of STD (both receiving and giving)? I am married and my wife is pregnant so should I be worried about having sex with her?
Thanks for all your help.
Welcome to the forum. I'll go directly to your questions.
A) Once in a while oral gonorrhea causes sore throat, and even more rarely tonsillitis with severe sore throat, like strep throat. However, over 90% of cases are entirely without symptoms. However, simply performing oral sex on men has been associated with sore throat. No specific cause has ever been found. The discomfort usually clears up in a few days.
B) Over 95% of urethral (i.e., penile) gonorrhea is accompanied by discharge, with or without uncomfortable urination, and you are correct about the interval, usually 3-5 days, but sometimes up to 10 days. Absence of symptoms within that time is strong evidence, but not proof, against gonorrhea.
C) Initial herpes symptoms usually start within 3-5 days, but it can take up to 3 weeks. You're probably in the clear if no symptoms at 7 days, but there's still a slim possibility.
D) In addition to gonorrhea and herpes, syphilis and nongonococcal urethritis (NGU) can be transmitted by oral sex. But I would suggest you should not be "worried about" them. Syphilis by oral-genital sex is rare, and NGU from oral sex probably is harmless.
E) The important issue here is that a condom was used. If it did not break, you can assume no risk regardless of the duration of exposure. Without a condom, the STD/HIV risk might be lower with brief compared with prolonged exposure, but it is not possible to estimate how much lower.
If your sore throat persists more than a few days, or if any other symptoms appear, of course see a doctor or clinic. Or if you like, you could attend in a few weeks for testing even without symptoms, just to be maximally safe. Your local public health STD clinic -- or its equivalent if you're not in the US -- would be an excellent choice.
I hope this helps. Regards-- HHH, MD
