A paraphilia is a recurring sexually exciting fantasy, impulse or behavior related to non-human objects e.g things, fabrics, designs, the suffering or humiliation of oneself or the partner, children or other non-consenting persons. So basically it is getting aroused by things that wouldn't arouse the average person. You have a paraphilia when you have these thoughts, behaviours and impulses for at least 6 months and they are distressing for yourself or others. We distinguish between fetishism, frotteurism, pedophilia, sexual masochism, sexual sadism, transvestitism fetishism, voyeurism, exhibitionism and other groups of sexual variations and unspecified paraphilias.
