Translations:Codex: Mothrine/19/en

Male mothrine had a large, hardened ovipositor-like penis and lacked a visible scrotum. Female genitals tended to be closer to Terran vaginas but more fitting for tube-like insertions. It’s wildly suggested that intercourse could last from anywhere between seven minutes to seventeen hours. It apparently wasn’t uncommon to sustain injuries given how light and potentially delicate mothrine features were and some more obscure references found in surface sites.
