I remember some comics from, I think, Deviantart, that were about animal courtship rituals, physical differences between the sexes and stuff like that. The animals were humanized, depicted as "naked" (AKA undetailed, it was totally SFW) cartoon people. The males were all blue, including their hair, with a Mars sign on their chests and the females were pink with a Venus sign and breasts. I believe there was a comic about hermaphroditic species (or maybe species that undergo sex changes after birth?), and the character for that was yellow, though I don't remember what symbol they had.
The only difference between characters of the same sex was in stuff like build and hair style or length. There weren't any recurring characters or storylines, just drawings accompanying an explanation of the biology involved. Each comic focused on a different species or characteristic. I think peacocks were included, and there was a comic about a species in which the female was much bigger than the male, but other than that I can't recall many details. The comic must be quite old by now, at least 4+ years but probably more.
