I am curious  about how the married and attached guys eould feel if their wives or girlfriends were in the hobby as well and I don't mean as a provider.  What if she were seeing straight male escorts like the Cowboys for Angels?  Would you be ok with it?  Shouldn't it be ok for her  to indulge as well?

If they do, this could get ugly.
I hope not.

.... because if it's good enough for me then dammit it's good enough for her too!!  

Realistically, though, there's a much better chance that the Browns win the Super Bowl in 2018 than my wife wanting to see male escorts.

Because my late wife was hot enough to get laid by a younger guy on the side without paying for it.  

Yeah, but like us, she would have been paying them to leave.
P4P, most of the time, takes the stalker /needy situation out of it

my own perspective has changed to that of a single man.  

Lol

What’s good for the goose...

A little strange every now and then is good for both.

As long as it doesn't cut in to my hobby funds.

If she ever wants sex i'm right there...in the bed already...and ready to roll.

In that sense your first wife is still screwing you every day.

I guess I'd be glad if she re-activated her libido and I'd like to think I'm not a complete hypocrite.
If she found a cheaper hair place she could really see some high-dollar guys.

Because A. - very little to no free time to herself to hide it (like me)
B. - while she is an orgasmic woman who is a tiger in bed wben we do, do it, she has such a low libido that its only about once or twice a month that she actually wants it.
C. - like someone said above - I am right here and available every damn day, she doesn't need to pay for it.  I do, hell, if I could afford it, it would be every damned day rather than once a month provider and 3 x a month SB.  I am a weekly dabbler.  Would be daily if funds and opportunity w/o getting caught could present itself.  But as I always say...  Friday is my day to play. (Yay! Today is Friday! I'm gonna get laid!)

.... saying to a friend, "I know my man, he would never fuck around on me."

I mean you can't ever be 100% sure, but even after we split up and were living in different states, I heard from mutual friends that she didn't start dating until almost a year after our break up.

Same, 99.99999 percent sure.  Never cheated first few years on her.  Wish I had neber gotten married actually now.

... (a really close friend), "I've given my man (or woman, lopaw!) permission to fuck around", or other words to that effect.  Some very understanding, loving SOs who don't have the desire and/or ability to please their men sexually but want them to be happy, so they outsource it.

It was still expensive, but a lot cheaper than if I had put it off for year after unpleasant year like many of the guys here have done.  

If you had a fulfilling physical and emotional marriage would you all still have to feed your old egos with p4p?

*wonders how much the men on this board actually knows about a woman's libido*

... there's many reasons people do p4p.  But if I got the physical intimacy I need from my marriage, I would never have started into p4p.  

And show me pics and something new when she got back.  Geeeeeeeez

Different standards.   In general, women stray when they fall out of love.  Men stray for variety.  So when a woman strays she's right at the edge of leaving anyhow -- maybe only money or security holding her back.  While a man can stray and not have any intention of ever leaving his wife.

More women in recent years are straying while still loving their SOs and remaining committed to them.  See for example the article cited in this recent thread.

I’m not sure how I would feel about that. I’d probably prefer not knowing.  My former spouse cheated and then ultimately married the guy she cheated with; not sure with how many she cheated before meeting him.  I got over it pretty quick and harbour no animosity.  

She fucked around on me before, and I was a bit pissed - but hey I was screwing around, too.

Good point.  
At the end of the day, my position on the original question is I would not be bothered if:
1. The men she is with are not in my circles in anyway
2. She is not negatively impacting my income or business in anyway
3. She is taking care of what she is supposed to do on the homefront and not changing her attitude
4. She is not negatively impacting the health of me or my kids  

Since having kids, we live more of a roommate existence and sex is non existent. Not sure how it happened but it has been years. Travel so much we don't even sleep in the same bed (also we both snore) and I found her ever growing dirty draw of vibrators. If she is getting some strange on the side (doubt she would pay for it) good for her.

it would allow me to be open and less guilty and sneaky about my hobbying, i think it would be fun for her/stress release, and i think it would make her more sexual in general which would actually increase the amount we have sex and decrease her self consciousness with it.

She provides at a legal brothel in a small Nevada town. She also sees both gigalos and female providers both with me and without me. I am OK with it. It is just sex. Sex is not love. I see other ladies and I love her more than ever. I know she loves me too. She has fun with others but she comes home and loves me and that is what important to me.

Same story here.  We are partners in many things...just not sex.  I know she sees some other guys to fuck and I am ok with it as long as it does not impact our family or home.  The only time we have discussed it (after deciding to have an open relationship) was when some Tinder-trash guy got pissd she would not see him again and threatened her by saying he was going to tell me about them and that he saved texts, pics and made videos...all that he was sending me.  I stepped in and made it clear that I knew my wife fucked him and that I also knew his name, his wife's name, where he worked and lived.  Needless to say, he crawled back in his hole like a whiney little bitch and we never heard from him again.

...But if I did have a wife, I wouldn't care. In-fact, I'd think it was kind of hot lmao.

I would be fine, but I wouldn't want to know who she was seeing.  

That would be great. It would men that she has an interest in sex and I don't have to keep spending so much money on P2P.
