"bob"

The common term blowjob is misleading, as blowing is not normally part of fellatio. A common technique is to take the glans 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. It should be noted that intense sexual arousal of the penis will often produce a small quantity of fluid from the urethra at the tip of the penis, commonly referred to as "precum". This fluid is produced by the Cowper's glands and is not semen (and has been demonstrated to contain far lower quantities of sperm than true semen). The purpose of this bead may be to cleanse the urethra and prepare it for the ejaculation of semen that may soon follow, as well as to provide lubrication for the foreskin and glans during foreplay and intercourse.
