Here is the link to a thread that is current on the 60 and Over board discussing the same matter.

However, I have seen some providers in their 30s lately, and found them just a mature and skilled as older ones.

 
Also, I have occasionally come across some mature providers who were not quite as mature in their behavior.

 
I don't think that age alone is much of a consideration in finding an enjoyable person to be with.

and I always seem to have a lot more in common with them. I do have a few younger clients that are more mature for their age and have had some great times together and conversations.

You’re going to hit more often with 40+ ladies if maturity is important to you. However, I have found ladies in their 30s and even mid-to-late 20s who are mature as well. If she is reviewed, I can usually sus out her energy. A younger provider who lacks maturity will show in her reviews, assuming she has a fair amount of reviews.

I've found anyone 27 on the low end and mid 40s on the upper end so far to be my favorite ranges. Younger than 27 for me doesn't give me as much maturity or fun. I haven't tried anyone over 46 yet not because I'm scared but exploring the MILF or GILFs would be new for me. But why not I guess.

it is probably fair to say that skills and engagement does increase with age -- particularly when the ages get closer to peer group age. That said I do find it's also much about professionalism and the mindset of the woman as I've had a number of very good sessions with women who are early 30s (and some even under 30) as well as some pretty unremarkable sessions with women over 40. I'm late 60s.  

 
A lot of factors go into a good session and not all are on the provider side, particularly when considering engagement with each other.

I've had far too many fantastic sessions with 25-30 year old women, and far too many unenthused sessions with women who were, shall we say, superannuated.  OTOH, yes, some young women in my experience who thought their shit didn't stink were so disengaged and aloof that I might as well have been fucking a mannequin. And there were some ladies in their late 40s and early 50s who made me say uncle--in a good way.

Experience and attitude matter at any age. If a woman literally has no idea what to do once the door closes because she's so nervous and inexperienced, no bueno. If she's become jaded and disaffected, el mismo. If she's let her body go, if she's unhappy, if she's self-medicating to get through a session, if she is robotic, same result. I think we can fairly say being a woman is hard work and being a good provider harder still. And while time undeniably takes its toll on the human body, my hat's off to all the ladies of every age who deliver the goods with care, thoughtfulness and enthusiasm.

i just saw a tryst ad for a provider that said she will not see any man over 50 or with a bmi over 34

fat old guys make this profession tick do they not?

You said you only recently started seeing young girls so is that a fair representation of them at large or is your sample size too small? Most of the women I see are 35 and under, with many being in their 20s, and I have great success with them, but that success comes with a big price tag lol.

I try not to get caught up in stereotypes. I find women I am attracted to physically and that happens to be mostly younger women. I then do my research to see if that particular girl in question meets my criteria with regards to her style, skills, personality, professionalism, etc.
.
There are many, many younger women who are amazingly skilled that know how to connect with an older man. You just have to do your due diligence to find them but that should apply to women of any age, right?

I prefer this newer mid 20s generation. Seem to love anal and really get into letting you do whatever you like. I regularly see a couple gals in their mid 20s

Ass to mouth is something they crave.  
Anal is full access. Gaping no problem.  

 
I think its the gen that grew up on internet porn.

And last year was my biggest hobby year for a variety of reasons. I tried it all. Plenty of trends. For age I’d say I enjoyed gals 25-35yo the most. I liked the attitude of many older goals but often not the energy.

I tend to avoid 20-somethings but nothing is set in stone. Last summer I met a 22 year old on the recommendation of a board pal, and she was amazing and on the wild side.  

 
In general though, my best times have been with women in their 40s and 50s and I've met some who had the body any 20 year old would envy. I've also found them to be very generous with many things.

Age can shape life stages, sure, but it doesn’t create or block connection on its own. Chemistry comes from shared experiences, compatible values, curiosity about each other, and the way two people make each other feel seen. Respect, humility, humor, and humanity don’t have age limits. Two people can be close in age and have nothing between them — or they can be years apart and spark instantly because they meet each other where it matters.

Every year, we are older, so it stands to reason that we will be more comfortable with an age gap today that is similar to that when we started.  I started P4P in my late 40's after my wife passed away suddenly, and found my sweet spot for a providers age was early-to-mid 30's.  As I got older, I found I was more attracted to women who were within the same age gap, so now, I enjoy my time with women in their mid-40's and occasionally will see women in their 50's if they take excellent care of their fitness and appearance like I try to do.  

The majority of women I've seen over the years from my mid-twenties through being nearly 50 now have been on the younger end of the spectrum (20s-early 30s). Youth has rarely if ever been an issue. Sometimes a young lady might not be as forward or assertive as I would prefer. Perhaps a little too timid in the moment. But that's been the exception, not the rule. And I've generally had the ability to create good chemistry with most of the women I've spent time with.

One of my biggest surprises came with an 18 year old provider I met around 11 years ago now. I was around 21 years her senior at that point, and she blew my mind. She was obviously very young, but near the end of the session I questioned her actual age. She went to her purse, took out her license, covered the sensitive info, and showed me her year of birth. Well a bit of quick math later, I came to the conclusion that she was indeed 18 years of age. And yet she made love like a woman more than twice her age.

I think it all comes down to us being flesh and blood creatures who despite having a job to do, can't simply turn it on and off if we're just not attracted to the person we are with. I've been fortunate to meet some of the most beautiful women I've ever seen in my life. And I happen to be a rather good looking man. I take good care of myself, and I'm charismatic. That along with my propensity to thoroughly research the providers I choose to meet, have enabled me to have mostly wonderful experiences. These women have been extraordinary lovers who admit that they don't treat all of their clients the same way. They will always provide the best service possible for the price being paid. But that doesn't mean that every man gets the same exact level of intimacy despite paying the same price. "YMMV" often applies.

And I think it's important to note that the larger the gap in age, the less likely it will be that a younger woman will find a significantly older man to be attractive. If she's really good at her profession, and she's genuinely sweet and kind, she's gonna try her best to go above and beyond. But it's probably gonna be tough to expect a young woman in her 20s or 30s to be fully engaged with a much older man. It's definitely a grey area. Because there's a lot of younger women who prefer to spend time with older gents. I believe it's due to a number of factors, from older men tending to be more emotionally mature, and not wanting to constantly pound the ever living shit out of their cooch. Older men also tend to be more affectionate and loving towards their partners, which kinda goes along with being more emotionally mature. But if the physical attraction isn't there for her, then you may not have her be fully engaged with you.

Perhaps just go back to what worked for you before. Older women are incredible. And if you've enjoyed better experiences with them in the past, then perhaps it would be best to enjoy the pleasures of the more mature versions of the female sex!

If it’s a one hour session where all focus is on the physical and you’re getting right to the action after a quick “hello, nice to meet you,” then age is totally irrelevant.

However, if it’s a 4 (or 6, etc.) dinner (and maybe other activity) date where there will be social time before the physical, a large age gap may be a problem. In such cases, there will be conversation beyond small talk. What will be discussed? Life experiences of course. And that’s where the “nothing in common syndrome” happens, and conversation can become forced and drag. For extended dates it’s better to be with a provider who is closer in age.
