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 the group of unspecified paraphilias.
