My freinds are kinda stupid

A while ago I came out to my friends as bi and they were chill but since then they have just assumed im every type of queer. One of my friends said I "look genderfluid" one time. On multiple different accasions my friends have told me they thought I was trans both FTM and MTF (I am a Cis guy). They keep saying i'm gay instead of bi, don't ask me why I don't know. Anyway it doesn't really matter to me that much just goobers being  goobers.
