Tribadism
'Tribadism' or 'tribbing' is a form of
mutual masturbation, sometimes called
frottage, in which a woman rubs her
vulva against her partner's body for sexual stimulation.
[1][2] The term is most often used in the context of
lesbian sex, but is not exclusive to such. Tribadism sometimes involves female-to-female genital contact, but more often refers to a female rubbing her vulva against her partner's thigh, arm or stomach. Sometimes the
labia majoras of one of the women's vulva will slip between her partner's labia majoras during lesbian sex. Tribadism can also refer to a
masturbation technique in which a woman rubs her vulva against an inanimate object such as a
bolster in an effort to achieve
orgasm.
The tribade
Tribadism was originally conceived of as lesbian penetration either with an
enlarged clitoris or a
strap-on dildo, generally performed by a "tribade". The tribade pre-dates the modern sexual identity of
lesbianism and was originally understood as a very virile female who could also penetrate males.
[3]
Today, "tribade" is defined simply as "a female homosexual" or a gay female. "Tribadism" is defined either as:
: 1. A plural for lesbian, lesbianism
: 2. "A homosexual practice among women which attempts to simulate heterosexual intercourse."

Tribadism among bonobo females
Females of the
bonobo species, found in the
Democratic Republic of the Congo, also engage in female-female genital sex, usually known as ''GG rubbing'' (genito-genital). It is the most frequent sex activity among bonobos. Females use GG rubbing to socially bond with each other, thus forming a female nucleus of bonobo society. While bonobo society is
egalitarian and less violent than many other primate societies, friendships among females organizes their offspring who maintain lifelong loyalty to their mothers. In this way, females often have more influence in group decisions.
