Translations:Codex: Kui-Tan/17/en

While capable of sexual intercourse at any point in time and also of conceiving on a monthly basis, hermaphrodite kui-tan retain the aspect from their more primitive ancestors of entering a state of heat approximately every six to seven months. During this time, typically about a week long, their hormones surge, giving them a marked increase in libido and a small, but noticeable, boost in passive semen production. This makes them markedly more interested in sex, though not so much so that they can’t resist the urge, as well as making it more likely for them to conceive.
