competitive worm grunting (worm charming) is a real thing

certain species of aquatic flatworms are hermaphroditic and engage in a mating behavior called "penis fencing" (https://en.wikipedia.org/wiki/Penis_fencing) where each of the worms grows a temporary penis and they duel with them, loser gets impregnated. Sometimes, both will pierce the other and they will both end up pregnant.

that's pretty obscure, right? thanks high school biology

that there is more blood in a boner then a baby rabbit. i think thats how it goes? im not looking that up😭 it still genuinely concerns me.
