Going back through my records, I find that yes, that was the most prolific year I  had, at least in terms of payout adjusted for inflation.   I only saw about 4-5 people around then, but spend a lot of time with them.   It was during that sweet spot when my wife didn't mind me foraging on my own, and my income peaked as well.  This was about 19 years ago when the economy was as roaring as it has ever been.

Best ever.

You are older than you look.  Much older.

49 is the peak spending year.  For average Americans their kids are out of college and off the payroll hopefully, the income is at or near its peak, the mortgage is mostly gone, creating the first time in a long time that discretionary income is very high.  So 47 to 52 would be the the years that you spend the most.  Making those your best mongering years at least financially

I don't have kids, and none of that other stuff really applied to me either, but coincidentally, 49 was quite possibly the year I got the most pussy, if it were not the year I got the most, those years from about 45 to my very early fifties I did fuck like a  drunken rabbit on Viagra. I think during most of those years I saw on average a couple of hundred different women each and every year, and routinely went on fuck fests where I would see a dozen or more different women on a three day weekend.

If I'm not getting some I'm giving it to myself.  

The last few weeks have been pretty damn awesome! I've had the pleasure of playing with exactly the women that I have wanted to play with as much as I have wanted to. Freaking amazing ladies.  
Vampire gloves, floggers, riding crops.  
GFE and just plain fucking.  
I'm 57, single and am doing just what I want.

That is based on research by Harry Dent.  His demographic research has been scary accurate, translating that to overall market trends also scary accurate..... boiling it down to when to buy a particular stock not so accurate lol.  Taking it to the next level of when should I book the next provider, I can answer that for you without all the research, do it when your cash is in hand and your dick is hard

Of course, I neither look like or dance anything like Patrick. But I'm having the time of my life.  

Started hobbying at 45 and went bonkers till the savings ran out.  Can't spill three cups now like I used to...many years later.  Back then people who know me said I would fuck anything that walked...and that was true.

50-55 for all the reasons listed by others.

2 kids in college with one more left. Interesting topic given this study http://www.economist.com/node/17722567 that suggests men are least happy in their mid-40s to their 50s

I pretty much done and seen it all.I now I see regulars every now and then...just not doing the crazy shit as before.

On this board, the other guys are going to call you "the kid."

I am spending more than I have ever spent. Taking it easy this December so as not to drain the finances before Christmas, not to mention, no time.  As far as being in my prime?  That was 25 yrs ago.

....I’d live that year again in a heartbeat!

My peak year as a hobbyist was 2012.  But the years since right up to this week, and back to '05, were and are pretty good, too.  I was 51/52 in '12.  But I was always a late bloomer...life's been good to me so far!
