Personally, no--I wouldn't buy it. Anonymity is important to me in penis enlargement products.
Even if you're going from big to bigger, like a lot of people here, the implication (or "judgment") is that you must have a problem with your size, and therefore you must be inadequate.
In the Non-Penis Enlargement world, only the "inadequate" would go to "desperate" lengths to enlarge.
But then again, we might be discussing a moot point if we're talking about the same market that would purchase an artificial vagina. I can only speak for me...
