Hemipenes (and penis/intermittent organs) are really diverse in terms of size and shape. A lot of lizards and snakes have little nodules and barbs that vary from species to species. Not sure what the ornaments do, but it’s interesting. Also interesting is that having two (i.e. one on each side) potentially means that there’s a handedness in terms of the preferred side used for mating.
Other fun facts about penises and other intermittent organs: cats and other felids have barbed penises that force ovulation in the female. Tangentially related are the pseudo penises of female hyenas.
More fun facts: damselfly males have intermittent organs that are spoon shaped so they scrape out the sperm of rival males.
Respond ‘cock facts’ to learn more about penises and intermittent organs.
Respond ‘stop’ if you don’t want to learn cool shit.

I see your “snakes have two penises” and raise you “kangaroos have THREE vaginas”.

Now I need to add a new nsfw “marsupial orgy” filter for when I’m watching pr0n (at work).
