I would take exception to most of these, or contend that sex with an escort leads to even better results, but I think this is pithy enough to generate some interesting discussion.

The only one I can't disagree with too much is #10, protection from STDs, but that seems to be a rarity in the P4P arena anyways.

And, of course, these 25 reasons only make sense if the spouse is indeed open to having sex still, which is often not the case.

I have BOTH lol. Escort and wife wrapped into one.

Kiss my hairy buttocks you all lmao

As you realize, it is aimed at young women and clearly is comparing (recently) married sex with catch as catch can sex from a young single woman's point of view out dating with all the complicating motives and insecurities that go with it.  
More interesting would be to compare sex in the hobby with the sex during a new affair.  I am just now pulling a bit away from an obsession with someone who got me to lose interest in the hobby.  A woman who was unbelievably sexy to me, presented herself as cool but was always horny, was delightful and intelligent social company, was up for anything sexually --except sharing-- and who shared a relationship with me during which (because of slight inconveniences like jobs and marriage) we could often not be available to each other.  
I compare that experience with my (very enjoyable) hobbying.  
I don't want to reveal of your secrets, but everyone knows you are certainly among the masters of getting the most from (and I judge giving much back to [the object of my obsession having pronounced you one of the most charming men she has ever met] ) your hobby relationships. One of these days we need to compare.  That would be a more fair comparison: me during the four or five years of my obsession and you during your admirable career.

Even my 2 runs at Newly Married Sex were problematic.  Only went down hill from there.  Married Sex Should Be Better.   But that presupposes that there is such a thing as married sex, or at least regular married sex.

I'm sure there's a few married couples out there that this applies to. After all, a broken clock is right twice a day. But the vast majority of the time, the kind of certainty you can place bets on, sex will be less and less frequent with every passing year.

Yeah there's a sense of comfort and security with it, the familiarity of someone you've been with for years makes it feel a lot better most times. Plus the lack of need for condoms is an added bonus. But you're only getting it 1-2x a month (at least from what I know of my two marriages and all of my married friends). Frankly if I have the choice between my SO's growing belly rolls and unkempt downstairs, and a tight younger escort who won't leave me with a mouthful of hair... you figure it out.

Glad to see there's a couple slides that boil down to telling girls to use their pussy as a bargaining chip.

A marriage is a kind of business with two partners who need to rely on each other to get their daily shit done.

If one of those partners thinks the other hasn't done his/her job right, they can decide to retaliate on another segment of the business, and that segment often turns out to be the sex.

So they get caught in a downward spiral of sabotaging each other's interests in the marriage until the thing either falls apart and they divorce, or they reach some plateau of mutual crappiness towards one another, and the sex is often the first casuality of that.

With the hobby, the business is simple:  Drop off the envelope, and you'll be assured of decent sex if you did your research well.

A marriage where both sides have their shit together and it functions well could have excelelnt sex for years, though the oft stated need for males to stray and women to become uninterested will still remain as obstacles.

Dr Joe ..I read your posting with big attention ... I feel a lot of intelligence and .. and pain to loose  this woman  as well as frustration that she was not able to share while was all for you ?? am I correct ?? and you needed this love you needed her vulnerability  and   even  not many wives can give to husband what he need to  feel a man .. and you know why >>it is a reason that we russian women are in  value .. we are giving more then just porno/ sex or intellectual conversation  we  give you YOURSELF .. we present you to yourself as lost valuable item you was looking for long time  and miss it .. with us you will find your meaning  as a male.. as a person in global meaning and in private intimate meanings ..it is why Russian women are loved .. not becuase they are .. you know wet .. sluts  only

But are you saying that Dr. Joe would not have undergone this disappointment if only he had been with a Russian woman?  

As long as both have the same views on frequency and kink.  Otherwise, it's disappointing.          

Don't care about the other 24 reasons, but number 25 makes sense. What was the best sex you ever had? Bet it was when you were head-over-heels in love. You know, the kind of love that makes your knees knock, palms sweat and heart race. I'm not saying that you can maintain this level all the time, every time. Married sex has ebbs and flows just like life. But when both parties are willing, you can have incredibly hot sex over the years.
