By rumour, Dr. Mauricio Goldstein, a retired porn actor and former lover of Rafael and now engaged in an aesthetic bioplasty enhancement practice in Brazil, is responsible for that celebrated "bubble butt"; and, too, by rumour, the gigantic cock of Dr. Goldstein's current lover, Mukhtar Satarov. The "Dr", however, does not imply that he has a medical degree, rather a doctorate in aesthetic enhancement.
