You know, this thread is starting to remind me of a quote I once read: "Everyone is puzzled, confused, and lost - even the experts. The experts are just one step ahead of the crowd, leading the masses in the dark."
Now, I don't want to go as far as calling us experts by any means. But I do believe you and I have a fair share of anatomical/PE knowledge between the two of us . . . And I'll be damned if we don't find ourselves more puzzled, confused, and lost the deeper we look
I think - and I've thought this ever since I learned about the smooth muscle in the penis - that the real problem is that for one reason or another, the community takes an idea and automatically passes it as fact (such as the penis not consisting of any muscle). It's human nature to hope for the best without any substantial evidence.
To get to the bottom, I suppose we must listen to Yoda: "we must unlearn what we have learned." That little green guy, he always seems to know the right words.
