Butt kissing is easy, making yourself interesting is a challenge.
Don't offer to submit to the first Domme who talks to you.
Many of us don't like being called Mistress by people not our collared subs.
Establishing a presence as an intelligent, dominant person will go far to bring you to the attention of the intelligent, PICKY subs as a Domme worth having.
Real power shows itself in politeness and in good manners.
Don't lead subs on to submit to you if you are just sub collecting for the heck of it, or if you have no intention of actually taking care of this person's well being.
Domming someone is a lot more than dressing in black and beating the crap out of your sub.
If you expect it to shift into real time, for gawd sake, try to find someone who has more to offer you than just D/s.
