Hi Bluegrass,
I have to say blindfold sex is one of my talents. Not something to do everytime, but it can lead to much pleasure in the right moment. I have enjoyed blindfolding girlfriends. I think it is a power thing, but there has to be a lot of trust to begin with. Once blindfolded, past girlfriends will usually adpot a more expressive and somethings different demeanour. Some liked to be controlled and experience things they may not feel as comfortabel doing if they could see. Sounds wried, but it is sort of allows them to be someone else and of course you to be someone in their minds too.
Also, the anticipation of not knowing what may happen next can be a huge turn on and 'norma' sex can be highten.
