most HPV strains will get cleared by the immune system or the natural desquamation cycle for skin.
they basically only lives on outermost skin and epithelium, however, some strains are more aggressive and stubborn and can cause warts that can eventually lead to cervical and penile cancers, usually due to repeat chronic exposures.
there are about a 100 known HPV strains, and about a dozen are considered high risk.
the sexually transmitted folks should worry about is HSV, Herpes Simplex Virus
type 1 typically causes cold sores, and type 2 typically causes genital sores, but they can cross depending on sexual practices.
these viruses are much more stubborn as they hunt down and invade into the nerves of the area around the initial site of exposure.
those nerves then shed virus particles in perpetuity, and sometimes relapse as full on blisters breakouts in times of increased stress or decreased immunity, the worst cases can cause bell's palsy, corneal keratitis, and meningitis.
