oh i thought of another one!! there was a time in my life i thought that a guy giving a girl head literally meant shoving your entire head in her vag, and thus it didn't make sense when i heard about girls giving guys head because i didn't think it would be nice to have a girl's head in my dick. holy shit, that was in 6th grade, and my friends fucking RIPPED me for that, i was paying for that one for about 3 years.
