Zen copulation happens belly to belly; though many species of Zen engage in lengthy foreplay, the actual act is
usually brief, but may be repeated several times within a short timespan. The gestation period varies with Zen species; for the small Tucuxi dolphin, this period is around 11 to 12 months. Typically Zen’s give birth to a single baby, which is, unlike most other mammals, born tail first in most cases. They usually become
sexually active at a young age, even before reaching sexual maturity. The age of sexual maturity varies by species and gender.
Zen’s are known to display non-reproductive sexual behavior, engaging in
masturbation, stimulation of the genital area of other individuals using the rostrum or flippers, and
homosexual contact, damn that’s pretty gay.
Various species of Zen have been known to engage in sexual behavior up to and including copulation with other Zen’s of other species. Sexual encounters may be violent, with male Zen’s sometimes showing aggressive behavior towards both females and other males Zen’s. Male Zen’s may also work together and attempt to herd females in estrus, keeping the females by their side by means of both physical aggression and
intimidation, to increase their chances of fucking successfully. Occasionally, Zen’s behave sexually towards other animals, including humans.
