Can hpv be spread onto your actual butt cheeks, not just anus? if so can you spread it through the toilet, please please clarify.

Unlikely to spread: if you maintain good hygiene , although it is contagious virus need repeated body to body contact . At 21 you still a candidate for vaccination . Speak to your doctor also a preventive measure for genital cancers .

Site specific: The various strains of genital HPV are site specific.In simple terms, they only go where they like to live & in this case it is the genital skin.There appears to be a direct skin to skin contact for these strains to transfer, so toilet seat transfer is a myth.
