I have to agree with Luke here - I a Bi male and a sub. what I need is the total hand-over of control to a Dom/me. anything like punshment etc. is only a phisical demonstration of this.
I also agree with "Mastersgem" regarding postion of authority held during 'Vanilla' Times - I have held very senior postions in some global companies. It is the power thing that does it for me not an abusive background etc. though without any research to back up my thought that this may be the case for most male subs.
Hope not to upset to many but thats my penny worth on this
