“For example, in the state of California, it is illegal to have sexual intercourse with someone under the age of 18; yet, in the same state, having sex with a dead body (i.e., necrophilia), does not have a specific criminal code within the penal system (Hickey, 2005).”

“Much like all other paraphilias, fetishes can be situated on the mild-to-severe continuum. An example of this range is depicted in the following scenario of four men, all having a fetish for women with long hair. The first man might have a mild fetish for women with long hair simply because he has always perceived the longer length to be more sexually appealing. The second man, functioning in the mild-to-moderate range, might whistle at and call out to an otherwise unattractive female with long hair yet remain silent when an extremely attractive woman with short hair walks past him. The third man, operating in the moderate-to-severe end of the continuum, might be unable to achieve an erection during intercourse unless he wears a long-haired wig or his partner has long hair. The fourth man might be able to attain an orgasm simply by looking at or touching the desired object. This behavior demonstrates that the individual functions at the severe pathological end of the paraphilic spectrum. The absence of deploying such fetishes in the extremely paraphilic-prone individual can cause erectile dysfunction (APA, 2000).”
