Our paraphilias of the week: Frotteurism and Toucherism. “Toucherism” might have given you the clue about the definition. Frotteurism is a paraphilic interest in rubbing, usually one’s pelvic area ... against a non-consenting person for sexual pleasure. It may involve touching any part of the body, including the genital area. Toucherism is sexual arousal based on grabbing or rubbing one’s hands against an unexpecting (and non-consenting) person. School districts of the not too distant future might want to get ready for the letters F and T.
