I nearly posted something a month or so ago along similar lines. Where some african tribes stretch their penises from birth. Remembered reading something along those lines in Encyclopedia...Funk and Wagnall ( :) ) some time ago, I think.. I suppose it proves penis enlargement, enhancement is an ancient, age old obsession. They use to roll it around a stick...each day or week they would increase the radius and stretch the cock further.
Much like rings around the neck, where in some tribes a long necked female is attractive...trouble is, it does not stretch the neck but lowers and deforms the shoulders.
