ya losing weight doesn't make your penis bigger, it just unearths it so to speak. it was always there, just hidden away in a bunch of fat. if guys actually wanna gain penis size...there is always something called jelqing. its like exercise for your penis. i don't really believe it myself, but even people like Sue Johanson (rockin canadian sex nurse) are starting to come around to the idea that it MIGHT work. it's worth a shot.
