Showering before sex maybe the routine for some people. Others like the idea of getting dirty during sex - literally - or making their partner dirty,. This fetish is called salirophilia.
Some salirophiliacs like to smear the makeup, mess up the hair, or rip the clothing of their partner.
Dr. Ian Kerner, a New York City sex therapist, says this often involves domination/submission fantasies.
