I don't believe it at all actually... I may .... MAY have thought of someone else in the throws of passion... but NEVER a mate.. let alone a female one!
Hold on - Do they mean that 13% of women have experienced such boring sex that they started planning their week and thinking "What is Alice doing tomorrow I wonder?" Lol
yer I know alot of people that fanatasise about being kidnapped and theres even a thing where you can set up to be kidnapped. But think of my mates no way.
