The job of being a mistress. Similar to how a waitress would say she performs waitressing for a living.
I've been mistressing with the same guy for 10 years now. The guy just can't get the balls to leave his wife.

Entity semanticly and physicaly highly related as per example below.

A Mistress is someone that stands between a "mister" and a "matress".

Mistress: "The Miss between the Mister and the Mattress"
My recent ex girlfriend told me she felt like my Mistress as athough my old relationship is completely over and has been for years, I am still a "room mate" with that person and our daughter as we sort things out.. I would see her, we would do things together, have fun, then I would have to come home to my house with my other ex still in it.. not the best way to start a relationship..

She got tired of being the Mistress while I was working on sorting things out..

I still get a chuckle when I think of this!

My Mistress is no more.. I'm gonna "Miss" her but am ready to find me another Mistress to be happy with!

A guy would actually have to have a lover/wife/girl to have a mistress. A guy who does not have one girl certainly does not have 2, and is therefore not a womanizer.
A guy who has never had a girlfriend his entire life has a hard time coming off as a womanizer even if he's trying. At some point people will find out the guy is not a pimp and doesn't really even know what to do with a girl, let alone a mistress.
