As an MD I agree with a couple of points:
There is not a significant disorder associated with penis size within a large range of what is considered normal. In general, any intervention is considered on its merits as risk versus benefit, and most docs would agree that the potential for small gains in size are outweighed by the risks (even though they are also small). Remember, these are professional considerations. I myself PE, and have seen gains, but would never advise a patient, because if something went wrong, I would get my ass sued off, because I couldn’t justify advising a normal sized guy to go off and hang weights off his penis.
As for research, remember, studies cost money. Who banks them? Two general sources: federal money and private money. No one is going to write a grant proposal to the NIH for penis enlargement. And private industry has NO vested interest in bankrolling a study. Why? They don’t have any federal restrictions to selling their products. First, there is probably no company large enough to have the cash reserves to blow. And why should they invest in a study and risk finding that it doesn’t work? A well designed study cannot have a set up that expects any particular result, so to be scientifically valid, a negative study is a real possibility.
Anyway, there is enough anecdotal evidence to support a careful, intelligently gentle approach. Not much to lose. And I’ve gained enough to be considered large by every partner I have had since starting. My newest tells me I’m the biggest she’s ever had at just over 8x6.5 in a cock ring, and she says her last three have been “big guys.”
START PE’ing!!!
