... my loving SO didn't specifically rule out the others. Her only conditions are that I don't bring anything home with me, and "don't fall in love."  So if "girlfriend on the side" implies falling in love, that's out, but b) is a possibility if I'd want to do it.  I just haven't felt the urge to go that route.

Girlfriend on the side is best (been there, done that.)

If you're both married to other people it is hot, hot, hot.  You're risking it all to fuck someone who is risking it all to fuck you.  You just don't get that kind of ego thrill from a paid escort (sorry ladies.)

What you do get from escorts is, of course, a level of beauty that most of us schmucks could never score in the civie realm.  

So does that count as "d"?

 
and yes, i can choose "none" because I didn't do any of this during the brief period of time (although it felt like forever) I was married.

 
BTW, I don't consider having two (or more) girl friends at the same time "cheating" unless you promised one (or more) of them that you would be faithful. You can't break a promise you didn't ever give. lol

Sure can choose None.   Never cheated on anyone in a civvie relationship.  
Very single and if I fall into a civvie relationship I stop doing this.  
If it lasts forever cool! If not I come back!

I started p4p in the last few months of the 2nd marriage till I ended it.

Since then, the only serious relationship I've been in was with a sex worker. I started as a client and it evolved into a pretty cool thing for about 6 months.  

Everything on my side was straight up. I wasn't going to be monogamous, and I hid nothing. As far as I know, she was the same. I always let her know I was playing with someone else and she let me know when she had a client (I never asked) or she was playing with someone else.  
I have a need to be able to be honest in a relationship, so girlfriend on the side is out unless she becomes a girlfriend for both of us. But,  
That freedom was amazing.

It helps that I don't get jealous often and when I do, I don't get angry about it.  

She once joked that if we were still together in 20 years, I would not be allowed to bring my young hookers into the house. I would have to play with them in my 5th wheel trailer.  

It was the most honest relationship that I've ever had. We both could truly be ourselves.  

It ended on a good note, and though I  miss her, because I really care about her, I'm happy she's moved on to improve her life.

My SO once told me she doesn't care if I cheat on her, but never get caught. Although she was joking, I took that statement to heart. I don't consider seeing providers cheating. It's like going to the dentist. My SO would beg to differ.

Most of my clients are married

And arent paying us ladies for sex, they are paying for us to leave afterwards (tongue in cheek) which is why they choose a provider instead of a gf on the side.

I playfully reply "not uh its my room, YOUR leaving" (im a sweet way) teehee
