I always have these feelings too... occasionally I want to Dom someone. I say try it out, see what happens. There are plenty of experienced and not so experienced male subs out there looking for a willing Domme so see if one of them wants to take you on.

A Domme is not necessarily, as Oz says, a harsh or cruel person. That is, in fact, the misconception most have of them. Most are caring and loving of their subs.

Maybe try talking to some male subs online, maybe indulge in a little online domination if you find someone you are comfortable with. Its ok, you won't betray your hardcore sub values by doing so...
