Help! Is this possible?

I’m in a strong marriage but looking to add something more for my caged hubby and I. He’s mostly a good boy (bratty at times), I really struggle with discipline and truly desire a FLR. I have him mostly under control but am looking for maybe a dominatrix with benefits. A girlfriend that means FEMALE ONLY gentlemen. A girlfriend if you will, to go shopping and dinning with at times. My other girlfriends just won’t understand and we have a strict rule our lifestyle remains separate from public life. Someone I can connect with that is more comfortable with establishing the rules and laying down the law when he gets out of line. Someone who can hold his key and I can snitch to monthly on over the phone. Please help is this a thing?
