Just a curious post wondering why everyone decided to get into the hobby if you wanna share. For me it's about having control over my sex life and not leaving it up to luck or another person. Imagine your really hungry, stomach rumbling, would you go to a random lake and cast your fishing rod hoping for the best, you either get lucky or don't eat tonight or would you just order takeout and eat till your full? Same mindset with sex. I do like to go out a lot and it's always fun when you get lucky here and there but making that the main source of sex sounds increadibly frustrating lol. As for "civie" dating I'm on and off but this hobby helps a lot cause I don't have to be desperate for sex I can get on demamd so no putting up with any bs in a relationship. I can leave whenever if I'm not satisfied and hobby instead, makes me feel bad for the guys I know who put up with toxic relationships and sexless marriages. Trying to get more friends into the lifestyle of freedom!

I just like having sex with beautiful women. Feels good and is a great stress reliever.

My personal reason is pretty simple i.e. guaranteed, no strings attached sex with gorgeous, skilled young women. All I have to do to enjoy that kind of amazing carnal experience is part with a little green paper. lol.

I do have a FWB sitch right now, and it's great having someone to travel with, grab dinner, catch a show, and just enjoy spending time with. So between that and my p4p dates, I feel like I have got the best of both worlds for now.

I really believe variety is the spice of life, especially when it comes to sex. I can't speak for everyone certainly, but I think monogamy has turned out to be a failed experiment for a lot of people. There are just WAY too many exampls to ignore.

Me and my SO are the best of friends and I would never leave her.
But I have a mental block about having sex with her  
We are ok without sex with each other...she may have a dude on the side... doesn't bother me as long as she acts as a wife to me.
So I see providers to help me stay married to my wonderful friend.
If she was to ask for a divorce, I would give it to her with no problem because she is an absolutely wonderful woman who deserves more than I'm giving her.
It's complicated!

Agree with a lot of the points of the OP.
Sex is a need that I want filled on a regular basis, but I don't want to sacrifice my entire life for it.  
I was married for 23 years and it was a terrible experience.  
I gave one person the power over my sex life, so I had to try to keep her happy.
As we grew older, we had less and less in common so she never wanted to do anything I was interested in. Then you are basically stuck, because you can't ask someone else.  It is all complicated.
This allows me to do whatever I want, with whoever I want, whenever I want without the complications of a relationship.
I get my needs satisfied whenever I want.  The only restriction is my piggy bank.  Then I can enjoy the rest of my life without someone holding me back or making me spend the weekend with her family.  I have lots of female friends that I can hang out with.  They actually treat me better because we are not dating.   They all think I am a nice guy because I am not walking around acting like a horn dog (because my needs are satisfied).  
Not to mention, escorts are much more willing to please me.  They don't treat BJs as some special treat you only get on special occasions.  
Then if you count the expense of a divorce, this is a lot more economical.
Once you get over the societal concept that sex should be with someone you love, this becomes a much more enjoyable way of living.
