Interspecies sex

Interspecies sex was the term given to sexual activity, including sexual intercourse, carried out between members of different species.

Etymology
Interspecies sex referred to breeding between species. The practice was euphemistically referred to as interspecies romance.

Practices
"Don't they teach you Twi'lek girls about protection anymore?"

- Kanan Jarrus to Hera Syndulla

Intimacy between species raised certain cultural differences and matters of etiquette; for instance the Twi'leks of Ryloth were highly protective over their lekku, which not only functioned as erogenous organs but as brain-tails storing certain memories. Lovers from other cultures were required to treat these head-tails with care during moments of physical intimacy. The prospect of interacting with species-specific appendages was arousing to some, and allowed for greater variety of sexual activities.

Humans were capable of engaging in sex with other Humanoid species such as Twi'leks, Gungans, and Wookiees. Sex between certain species could result in interbreeding without sufficient preventative measures, although not all species were capable of conceiving through sexual intercourse. While Twi'leks and Humans could engage in sex, it wasn't thought that the species could procreate.

Society and culture
Interspecies sex was illegal under the morality laws of the Galactic Empire, making it taboo for Imperial officers to participate in or watch, which gave rise to jokes about the Imperial Security Bureau's Censorship Division being the perfect assignment for perverts and deviants.

Behind the scenes
Shabby Blue first depicted an instance of interspecies sex in erotica canon with his pairing of the Human Padmé Amidala with three Gungans in SBAOTC76 - Wedding Shower.
