"Sometimes, I like to rock out with my cock out. The ladies love it!"
What in the hell is Peodeiktophilia?
Peodeiktophilia is a paraphilia of the solicitational/allurative type. Peodeiktophilia is the act of exposing the penis to cause some sort of surprised reaction from the "victim." The reverse condition, staring at the penis so to speak, does not have a specific name but falls into the much broader fetish of voyeurism. There is no term for the female form of this fetishistic behavior. The old man stroking himself at the window of a fast food restaurant, the young man stripping and shaking his genitals at a crowd, even the politician (Weinergate anyone?) are all forms of peodeiktophilia.
In my search to discover causes of peodeiktophilia, the evidence was nearly non-existent. I would assume that just like exhibitionism, the act of surprising or shocking someone with your genitals causes a huge rush of endorphins due to fear of being caught, and possibly even the predatory nature of the act. While not inherently attacking anyone, the exposing of the genitals to an unsuspecting person will almost always result in some form of surprised reaction, and is definitely considered a sex offense. While I found no treatments specific to this paraphilia, the following therapies could have various degrees of success in treating the condition:
Cognitive Behavioral Therapy: altering the thought patterns that make the "performer" derive pleasure from this act.
Orgasmic Reconditioning: retraining the performer to orgasm to a more acceptable stimulus by having them masturbate to the thought of exposing themselves, and then focusing on something more acceptable before and during orgasm.
Several different forms of group therapy: Using the group experiences to recondition the performer into being able to control their urges, or find alternative outlets.
I have personally experienced peodeiktophilia. While working at a fundraiser at a local restaurant (a drive in), an elderly man ordered his food...and as I walked up to deliver his order he pulled his penis out and demanded that I look. Of course, in pure surprise...I dropped the order and started laughing. It drove the man insane. His power had been taken away. I still laugh to this day about that event.
Other people may experience it at a sporting event, in a store...or even in their home. It can be hilarious as it was for me, or it can completely scar a young woman who has never seen a penis (let alone being surprised with an eye full of male genitals). Don't be entirely surprised if you run into this at some point, but let it be known that this is also done as a "game" between young men.
