A paper published on December 16th 2014 titled “Body integrity identity disorder (BIID): How satisfied are successful wannabes” by Sarah Noll and Erich Kasten took a look at how satisfied people suffering from BIID are after surgery, where they intentionally choose to remove a perfectly healthy body part. People suffering from Body Integrity Identity Disorder feel the intensive wish for an amputation of one limb or another kind of handicap. As the authors write in their paper:
There are some parallels to the Gender Identity Disorder, in which people have strong feelings that their outer sexual organs don’t fit to their mental identity. From this point of view, Prof. Dr. Michael First  concludes that this phenomenon has to be called “Body Integrity Identity Disorder” and should not subsumed under the older term “apotemnophilia” as a paraphilia, which had turned the focus on a sexual component . Without any question, several of these persons have erotic feelings in respect to amputations, but this sexual component is not found in all individuals with BIID [12, 13, 14]. Currently McGeoch and co-authors  named this syndrome “Xenomelia”.
I wrote about BIID before in relation to “Gender Identity Disorder” in my post “On Gender Pronouns, Gender Identity And Transgender People”:
For example, I mentioned “transabled” people above who suffer from Body Integrity Identity Disorder (BIID). Well, it comes as absolutely no surprise to me that these people “sometimes have a sense of sexual arousal connected with the desire for loss of a limb or sense” (Brugger, P; Lenggenhager, B (December 2014). Clearly “transabled” people suffer from another one of the consequences of sexual suppression and repression in society.
And here’s what the authors write in their paper:
3.2. Erotic Component
Several, but not all subjects wrote they feel an erotic component as e.g.: “In puberty there came an additional sexual component of about 50% weight.”; “In addition the stump is erotic.”; “When my first wife suffered from an osteo-sarcoma and lost her left leg, my life was perfect. The stump became part of our sexual satisfaction.”; “There is an aesthetic sexual complex, in addition I find the kind of walking very erotic.”; “The otherness, the stump stimulated me. Pretending always resulted in masturbation”
In addition, after the surgery involving removal of their limbs, the authors found that sexual satisfaction of the individuals involved went from 15.2 ± 25.2 to 35.2 ± 22.5 (on a scale of -50 to +50). An improvement of almost 100%.
Like I wrote before, “this just goes to show you how right Dr. Freud was, to what extent the sexual instincts ‘can change their aim,’ and how perverted and warped other means of sexual gratification can get when people aren’t allowed to freely satisfy their sexual desires in a natural way, starting from early childhood.”
