How to turn a guy on in the bedroom. Confidence is important. You don't want to hide behind the curtains, or dive under the sheets when the lights go out. A woman who can walk around naked shows that she is confident and this is a major turn on. Also, when you understand a man's body and know what to do with it, this is also a major way to turn a man on. Be yourself, you don't have to act like you are in the movies and be all dramatic, like a porn star. You shouldn't be afraid to do what you need to do.
