Headcanon: denki and mineta would flirt with midoriya as a joke, (mineta literally admits feelings while trying to get izuku back from vigilante arc tho…) so izuku would find out about some “stuff.” Also Mina would traumatize him with THOSE kinda fanfics bc he has funny reactions. This comes to my conclusions Izuku is actually kinda 𝓯𝓻𝓮𝓪𝓴𝔂 while katsuki doesn’t know what “smut” and “lemon” means. This is a joke lol
