Oral sex

For oral sex on a man see fellatio.
For oral sex on a woman see cunnilingus.
Oral sex is when one partner uses the tongue, mouth or throat to excite the other partner's sex organs. For males it can include placing the penis in one's mouth and for females licking the vulva.

Sometimes oral sex is performed as a way of getting ready for intercourse, but it may be done as an alternative to intercourse. 

If someone is performing oral sex on a male, he or she may decide to swallow the semen if the male ejaculates in the mouth. There is no risk of pregnancy from swallowing semen.

One can get sexually transmitted diseases from oral sex, such as herpes simplex (which can be passed between mouth and groin or the other way). Some STDs, like HIV, are much harder to pass through oral sex, but it is still possible.

The technical term for oral sex is fellatio if performed on a male and cunnilingus if performed on a female. Slang for oral sex is common in Western cultures, for example: "going down on" (for both genders), or "giving a blowjob" or "giving head" (referring specifically to Felatio), or "eating out" (referring specifically to Cunnilingus.)
