Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure. Other forms of anal sex include anal fingering, the use of sex toys, anilingus, pegging, as well as electrostimulation and erotic torture such as figging. Although anal sex most commonly means penile–anal penetration, sources sometimes use anal intercourse to exclusively denote penile–anal penetration, and anal sex to denote any form of anal sexual activity, especially between pairings as opposed to anal masturbation.
Fellatio is an oral sex act involving a person stimulating the penis of another by using the mouth. Oral stimulation of the scrotum may also be termed fellatio, or colloquially as teabagging.

Genital herpes is a herpes infection of the genitals caused by the herpes simplex virus (HSV). Most people either have no or mild symptoms and thus do not know they are infected. When symptoms do occur, they typically include small blisters that break open to form painful ulcers. Flu-like symptoms, such as fever, aching, or swollen lymph nodes, may also occur. Onset is typically around 4 days after exposure with symptoms lasting up to 4 weeks. Once infected further outbreaks may occur but are generally milder.
Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration.

Some forms of non-penetrative sex, particularly when termed outercourse, include penetrative aspects, such as penetration that may result from forms of fingering or oral sex.

Its contents are divided into four sections: "Cunnilinctus" written under the pen-name Roger-Maxe de la Glannege and published by Jacob Brussel of New York in 1940; the three remaining sections "Fellatio", "Irrumation", and "Sixty-Nine" were not published until 1969.
