Mr. Answer Man says: Because forbidden fruit is the essence of temptation.
But give a guy a break. Somewhere between the devil on one shoulder and the angel on the other lies a place where your guy entertains notions that he would never, ever act upon. We use the word fantasy because they're not real, nor do we wish they were. They simply overtake us every now and then, command our attention momentarily, after which we return our focus to you. Because, simply stated, the relationship is real -- and fantasies are not.
But consider this: Is it at all possible that you've shared some of the juicier details of your relationship with your female friends? Perhaps also, you've told your man about some of your friends', um, proclivities? And if so, will you admit to the possibility that some of the images dancing across your partner's brain were put there by you?
What do you think? Let us know, and ask Mr. Answer Man your own questions here. Do all men have the same sexual fantasies?
