Thanks for this question! I really tried to find an actual reason (without the stop signal answers like "culture" or "religion") and found following (it's probably highly flawed, but at least worked for me):
Clothes were invented for protection and convenience -> civilization development created social disparity -> poor and slaves couldn't afford clothes -> nakedness ≈ slavery and slaves were the easiest source of sex -> it's shameful and dangerous to be naked -> shame and abscense of genitals around free people sexualized genitals -> slavery slowly becomes illegal in the vast majority of cultures -> majority of people already conditioned that naked opposite genitals ≈ sex, nudists are minority and not mainstream -> with such conditioning (or simply, culture) we can't have common bathrooms.
Btw, prisoners rape prisoners regardless of genitals.
