Welcome to the forum. There are many forms of necrophilic activities and schools of thought. They run the gamut from a simple fascination with crypts, caskets, funeral rituals through the ages and so forth to physical/romantic necrophilia (i.e., soft touching of the corpse) to ritualistic necrophilia (certain Satanic rites fall into this category as well as elements of Palo Mayombe and left hand Tantric practices), to sexual-erotic necrophilia (i.e., intercourse or other blatantly sexual activity with the dead) to violent outbursts against a corpse (i.e., Sergeant Bertrand is the best example of this type of person). Don't rush yourself; just take it at your own pace and accept what fits and reject what disturbs.
