I read the that the thing about the silk pillows is a myth.
This is good that it's so popular though, because that will only make advancements happen sooner and the price will drop most likely. The thing about it not being able to hold up well if you sweat is problematic though, because a lot of guys are getting these just so they can appeal to the ladies, but when you take her to the room with you, you're going to sweat once you get down to that action. That's got to be kind of embarrassing and stressing for your ego. That stress can't be good for your health.
