Your almost there...Mine thought same thing and said exact same thing about fantasizing about other men but couldnt picture doing it real. Then one day she ran into a hot younger guy who wanted to bed her and one thing led to another and hes fucking her and she comes home and tells me we need to be in an open marriage. Could have gone bad but when my wife earlier shared her fantasies I told her it was a huge turn on....so she didnt go seek it out but eventually a man is gonna want to bed her and shes not gonna stop them.

They often have a hard time picturing it but in the moment their hormones get the best of them and if they are already fantasizing about it then its only a matter of time and opportunity and its going to happen.
