I don't know if pe works or not. I hasn't been proven to my satisfaction, but neither have many other commonly accepted ideas. I really don't know.
Again, I'm not downing pe, or dismissing it as bull. I don't have enough info
yet. The argument "can so many be wrong" is very flawed. Just look at all the crazy religions in the world. It's all in what we have be taught to believe over the years. What you, or I, believe doesn't make it fact.
Is your interest in whether PE works or not just out of abstract curiosity, or is this something that you would consider doing if it was proven to your satisfaction?
I will relate the reason I ask to my experience. For me, starting PE took a leap of faith. Men hear all their lives that your penis size is your penis size, and there is nothing you can do about it other than accept it. Penis enlargement pill e-mail spam is widely loathed, and use of devices is something that is employed to comic effect (Austin Powers).
I happened upon Thunder's Place, and started reading. What helped me start PE is that at Thunder's, there was a huge volume of posts. Many men had gained, some had not. And Thunder's did not charge anything to join, and was not selling anything. I asked myself the question, "Could so many men spend so much time posting here without there being SOME grain of truth to it?"
And, of course, the answer to that is of course, they certainly
could spend all that time posting without any grain of truth whatsoever. However, they also have a Newbie Routine there that seemed pretty innocuous. No pills, no devices; just an investment in time and effort for a limited duration.
So, I started PE, knowing that if it WAS going to work, I needed to give it a fair chance by following the routine as closely as I could.
And it worked for me. I gained.
So, if you are genuinely interested in PE as something that you might do yourself, I would suggest that you start by doing some reading at Thunder's Place. The forums have just re-opened for new member registration, so join so that you can get full access to the site. In that way, you may arrive at a place where you can give it a try with an open mind.
And if your interest in whether PE works or not is purely hypothetical, I think where you are now is just fine in thinking that "maybe it works; maybe it doesn't". There's no reason to spend a lot more time thinking about whether it works or not unless you are actually considering it for yourself, or unless you want to become a crusader against it, warning everyone who mentions it about the impossibility of it all.
