"Moe-sexual" is a term primarily associated with Japanese otaku culture and specifically relates to the moe phenomenon in anime and manga. It describes a specific type of attraction, often characterized as a "maternal affection" or a desire for protection and care towards cute, innocent, and idealized characters, particularly female characters. It's important to note that "moe" is distinct from typical sexual attraction and is often described as a non-sexual, pure love or admiration.
