Ferrets are unisex and have skinny prehensile penises, a single cloacal opening, and a vagina. Like humans, their body is almost always ready to have kids, and they usually release a two-egg structure into the oviduct every other week. If not fertilized the egg mass is pushed out during bowel movements. During sex they mutually place a sticky packet of sperm in the others’ vagina, which melts in the body and fertilizes the eggs. The eggs will develop into a 2 chamber egg case with a single shared yolk. All ferrets are essentially twins! The egg case is also shaped like a heart and bright magenta.
Common methods of birth control are hormone tablets and vaginal condoms, because penis condoms don’t work great on a flexible structure. Homosexuality is. Not… really a thing ferrets have a concept of, but most sex takes place in groups of 4 or more, as most family groups can have anywhere between 8 and 30 adult ferrets. Manual stimulation is enjoyed, but like avians they have pinchy nightmare mouths, so no oral. Anal sex is a relatively common activity, although frequently frowned upon for being potentially dangerous to the intestinal walls. Like humans, it’s safe enough with sufficient lube.
