Oral sex
consists of all the sexual activities that involve the use of the
mouth, tongue, etc., to stimulate the genitalia. It may be used as
foreplay before intercourse, or as climax of a sexual act.
Fellatio
A common technique of fellatio is to take the glans (head) of the
erect penis in the mouth while rhythmically caressing the rest of the
penis with the hands; the testes and the shaft of the penis can also
be licked with the tongue. Suction is often used to increase the
pressure and friction exerted on the penis. (When the testes are taken
into the mouth, the act is sometimes known as "teabagging" due to its
supposed similarity to the action of dipping a teabag). Depending on
the preference of the participants, this stimulation may produce an
orgasm and ejaculation of semen which may or may not be swallowed,
hence the phrase "spit or swallow".
While the use of the mouth to stimulate the penis, especially the
glans, is a central feature of fellatio, often the partner
simultaneously stimulates the shaft of the penis with her/his hand to
provide the man with the feeling of the penis being enclosed.
The practice of passing semen from the mouth of the fellator to that
of the fellatee, or to the mouth of another participant, is known as
snowballing. However, if the partner is unwilling to swallow or allow
the semen into their mouths (and spit it back out), a common variant
consists of the fellatee ejaculating over the fellator's face/body.
The slang term for this is a facial. Some couples prefer the facial as
an act of sex play and not of an unwillingness to swallow. If the
ejaculate is squirted on the neck/chest of the fellator, it is known
as a "pearl necklace".
A technique requiring significant skill is known as deep throating,
named after a 1972 pornographic movie which features it. This
technique involves taking the entire erect penis in the mouth, the
shaft bending slightly to allow the head of the penis to slide
partially down the throat of the fellator.
The practice of using the teeth covered by the lips during fellatio is
known as t-boning. Though some males find the sensation of teeth on
the penis to be arousing, if done incorrectly it can be painful or too
intense.
A small percentage of men have the penis length and/or body
flexibility to fellate themselves, or to autofellate.
The common term blowjob is misleading, as blowing is not normally part
of fellatio. In fact, blowing air into a partner's penis is an
unhealthy practice. The opposite, sucking, is much more appropriate.
Cunnilingus
Cunnilingus is the act of using the mouth and tongue to stimulate the
female genitals, especially the clitoris. The term comes from an
alternative Latin word for the vulva (cunnus) and from the Latin word
for licking (lingere). Some 33% of women report never or seldom
achieving orgasm during intercourse, and cunnilingus is a way for many
women to achieve orgasm with a partner.
As in all human sexual behavior, the variety of techniques in
cunnilingus and individual responses to them are almost endless. As
always, communication, experimentation and practice are the best way
to learn how to please a particular partner.
The clitoris is the most sensitive part for almost all women, but may
be too sensitive to stimulate directly at times, especially in earlier
stages of arousal, and it's often best to begin with more gentle and
less focused stimulation of the labia and the whole genital area.
Tongue tip, blade or underside can be used, as can the nose, lips and
teeth (with caution). One can suck, sip, lap, nibble, etc. Movements
can be slow or fast, regular or erratic, firm or soft, as the moment
requires.
The tongue can be inserted into the vagina, either stiffened or
moving, and someone with a long or very flexible tongue may be
jokingly considered very desirable. This can be combined with
stimulation of the clitoris by the nose, if one's facial proportions
are appropriate.
