i'm not really a pain s*** ... for me it would be more of a day to day thing and go far past the punishment 'ooh ive been a bad girl' crap.
Truthfully i would imagine being a f/t dom/me to be amazingly difficult. I worked for a domme for awhile and she had to constantly take her sub's emotional and physical needs into consideration. Sure he kneeled down to her each day he came home, serviced her as she required but like many subs, needed constant reminders of his importance etc. Subs can be a fragile lot.
