about femboy horniness and sexualization

about femboy horniness, i was discussing a shitpost with my friend and used a sticker of astolfo, then he went 'hell nah', i asked him why does he dislike femboys, he told me theyre hypersexual, very horny etc. i went on to but i think femboymemes is too unreliable as a source for this (a top result) and then LOTS of quora 'gay if X femboy', and so on, i went on to askfemboy and asked but it seems to be a dead forum

i told him id ask over on reddit as far as im aware, many femboys here

so my quesiton being: why, why not and how are femboys so hypersexual, or are WE misunderstanding something

also my question might sound very dumbed down (and reasoning) due to forum rules
