I am kind of curious about how often some people hobby.
So... Some questions
How often do you visit a PO? Let's say per month? How often do you meet a new PO?
Personally, I have gone out twice in a month. Still new, super fun though
Everybody is different in their needs, wants, availability (of themselves and ladies they want to see) and budgets. For me personally, I have gone from 4 appointments the same week, to one appointment in 4 years.
Once every few months. I'm not rich and my tastes require high class ladies lol.
I think the most I've seen was six in one day, most days don't even come close though. lol
But seriously although my personal record is forty different providers over a ten day period, I would say that I like to get laid at least once a day, but that doesn't mean that I book an appointment every day with a different provider, but I will say that most of my sex comes from P4P, and that I do try to get laid at least every other day at a minimum. I think that's a pretty healthy number at my advanced age of 55. I am sure my appetite will wane as I get older, but I hope not by much.
FWIW, I am hardly new, but still consider this super fun after decades of doing it. Welcome to the party
In my post above where I said, "from several in one week to one in several years," I almost said "from 40 in ten days to one in several years." 
So actually in my case it goes from several each day, to none over a five year period, which was the length of time I was with my ex wife.
I also stop doing this whenever I get involved in a "committed relationship" although I guess it's kind of a gray area when I get involved in a committed relationship, but do so with a hooker.
I have a question. Are you still "in the hobby" if you are only seeing one woman, not for pay, but said woman happens to be a hooker???
Right now, it's twice a week. It's been more when I'm traveling, like 4 dates in a 5 day window. Once, two dates on the same day.
What will guide you ultimately is your budget and schedule. I'm hoping to 'normalize' in the New Year to 2-3 times per month, but I also fear I'm kidding myself! I have several ladies that I see regularly when they visit my city, like once or twice a month, with a new provider seen maybe 2-3 times per month.
My schedule is all over the place between work and kids (divorced). So sometimes I will multiple times in a week, and then go weeks with out. It all depends on my availability and my mood. When looking for someone that would fit my personality, I once saw 5 providers in a 3 day period.
Which so far has been 2-4 times a month
but it varies.
I saw two ladies in the last week.
I also go to AMPs about once every 5 weeks or so.
I get legitimate massages once a week too, those were actually my gateway to seeking other "fun" experiences.
One of my two regulars gives the most sensuous "legit" massages possible, covering every square inch of my body other than my cock, extensively rubbing my inner thighs, pubic region, etc, and with lots of bumping against my cock. And she enjoys arousing me and teasing and commenting on it - but she never crosses over the line technically, well except for a single tug or two awhile back while we were joking around, but I respect her boundaries and don't even ask her to do that anymore. This lady does understand sensuous touch. So nice to stop by and see her on the way home from work for 90 min of pure sensuous relaxation. For a little over $100, it is the best value for the $ I've got going
providers on back-to-back days and other times several months go by before I can indulge.
When I first started and during my more active period in the early-mid 00's I saw 2-3 girls per month.
Most I ever saw was 6 girls in a month and I think three of those landed on the same week.
When I started back up in '11 due to less time and lower hobby funds I averaged one girl every 3 months or so.
Lately I had a good turn at work and more time on my hands so since mid August I've gone back up to 2-3 girls a month. Although I know it won't last and I'll have to pull back somewhat again soon it's been a fun ride.
