Guys, at the risk of sounding like a schoolmarm I must protest at the use of the word "rape".
What is being described here is NOT rape but "rough sex" or possibly "rape fantasy".
The obvious difference is that it is consensual with control firmly in the hands of the "victim" and it is undertaken for the pleasure of both parties with their mutual pleasure as the goal. It can include rough handling, props like handcuffs, masks, whips, ropes etc but it is still only a game played by consenting adults.
Rape, or "sexual assault" as it is described in the criminal code, is the most degrading form of attack a woman can suffer at the hand of a fellow human. It usually involves violence and the kind of mental torment that some women never recover fully from.
I hope that none of the lovely ladies who post to this board ever discovers the difference at first hand.
