What STDs can be transmitted by oral sex? Do you have advice for safe oral sex?
STDs (sexually transmitted diseases) that can pass from one partner to another during unprotected oral sex include herpes, gonorrhea and syphilis. And although no documented cases are on record, from what we know about the transmission of HIV (the virus that causes AIDS), it seems it must be added to the list, too. (HIV is present in male ejaculate and pre-ejaculate.) Also, it’s theoretically possible, but highly unlikely, that you could get chlamydia in your throat from having oral sex with an infected male partner.
The herpes simplex virus is very transmittable. The virus is spread through contact with lesions or fluid in lesions; it can even be spread through contact with an infected person who has no symptoms. There are two varieties of herpes simplex virus — Type I typically infects the facial region and Type II affects the genital region. Type I can be spread to the genitals during unprotected oral sex.
With a male sexual partner, the regular use of condoms is a good first line of defense against STDs, since condoms provide a barrier against body fluids. Likewise, safe sex experts recommend latex dental dams as barrier protection when performing cunnilingus. Remember, though, that if your partner has herpes lesions on uncovered areas of the genitals or mouth, you are still at risk for contracting the virus if your mouth comes into contact with them.
Your lover is at greatest risk of contracting an infection from you while you are menstruating, since HIV is found in highest concentration in the blood (it can also be found in vaginal and cervical secretions).
My advice? Use condoms, dental dams and caution until both you and your partner get tested.
