I have never experienced a blind masseuse however I have experienced (on my request) a totally blacked out room where you can't see your hand an inch from your nose. I have been both the giver and receiver in this situation. I do enjoy this type of session ever once and a while. It allows the other senses to take over a bit. You eyes never need to be closed because they give you no feedback. The biggest problem is remembering where you placed the oil the last time you used it. *S
PS I have done this where we never see each other until after the session.
