pr524, i guess no one who has experienced this has seen it to respond as yet. my one brother has this, but it is assumed that is was inherent disorder.
i did a wikipedia search on it and found an interesting explanation. i won't publish a link here because there is a graphic depiction of an erect penis with peyronie's [not sexually suggestive] and if people here click such a link they may be triggered by what they see. not good
so you are welcome to go ahead an google wiki if you want, just wanted to add the trigger.
