In/Out and STD

Nov 27, 2001

Hi Ryan

Kind of an odd question, but here it goes. Put my mouth AROUND (not exactly on) a flaccid penis for about a second, barely touched my mouth. I know that the risk for HIV is negligible due to exposure time and lack of fluids, but what about other STDs?

Specifically, do the first signs of an STD always appear at point of contact? Meaning, if one was infected with, say, gonorrhea, would it manifest in one's mouth, or the typical "burning pee."

Would any and all STDs in this case manifest in the receptive person's mouth?

Thanks very much.

Response from Mr. Kull

General questions about sexually transmitted infections or STDs are difficult to answer. The category is so broad and simply describes a bunch of different, unique infections that are normally spread through sexual contact. This makes it hard to generalize.

Basically, it sounds like you are at very low risk for any STDs.

Different STDs will take different amounts of time to manifest symptoms in the same person, and can also vary from person to person. Many people will not experience any noticeable symptoms when infected with certain STDs.

STDs that cause discharge or burning (like gonorrhea or chlamydia) will manifest symptoms in the area of exposure (the vagina, penis, rectum, or more rarely in the throat). They do not travel from one location to another, but can occur in multiple locations at one time; this is because people might do a lot of different things with their sex partners.

Some STDs that are present as sores or lesions on the skin, like herpes, HPV, and syphilis, may be transmitted to you by having oral contact with the infected areas. Other STDs that are transmitted by fluids or infected mucous membranes in the penis, like gonorrhea, hepatitis B, and syphilis, can also infect you orally.

There are certain sexually transmitted diseases that can be transmitted to your genitals via somebody's mouth. Any infections that occur in or around the mouth, or are transmitted through fluids in the mouth, could theoretically be transmitted to your genital region. STDs that could be transmitted through RECEIVING oral sex are herpes, syphilis, hepatitis B, gonorrhea, and HPV.

Oral-to-genital and genital-to-oral transmission is probably not as common as genital-genital, but it can happen. If you need to learn more about STDs, symptoms, detection, and treatment, see the STD Basics at The Body (
