deviant sexual behavior:

Or: deviance / deviation / sexual-deviance / sexual-deviation / sexual-deviancy , sexual-behavior that diverges from the accepted norm or what is regarded as ' normal ' by a community. Examples range anywhere from homosexuality to oral or anal-sex to exhibitionism, voyeurism , pedophilia, incest , zoophilia , fetishism , sadism , masochism , transvestism . This expression and its synonyms is mildly pejorative (what deviates is not straight) and the expresions variance / variant-sexual-behavior / sexual-variance are preferred by sex educators and sexologists because they are neutrally descriptive and non-judgmental.
