I have a very small number of people that I visit as regularly as I can. It's an interesting question and I'm waiting to see what others have to say about it.

Is 6 to 10 considered exclusive?

I have two that I see monthly, and 3 others I see about 4 times a year, then another five or so that I see once or twice a year.

But I have known most of them for ten years or more.

one regular for years; occasional other but never as frequent

Have 1 SB that I am exclusive with. She is poly and I am open to something. Haven't tried a threesome yet with her.

Since I retired I have settled in on seeing two to three different gals in town----it is different when you are traveling to various cities---when I was traveling a lot I tried to get set up with a gal in each city that would be my regular when in town---all for convenience, familiarity, and reduced possibility of something going wrong---like the police or a pimp  !

Thank you, kindly for sharing!

Friends with mutual benefits.

I see someone about 12x year for now 11 years and there’s a great comfort level and predictability, including her tendency to cancel on short notice- but I keep going back. There is one other I see about 5x year. Maybe 2-3 x year I see someone new.

Not for me, but my long term friends are dear dear people to me.    

Actually I think it’s possible to have experiences and intimacies in this lifestyle that are valuable but rare in “civilian” life.

Monthly Arrangements

I have had them all semi-exclusive, totally exclusive & off the market.  

I think the best is always having dates on the calendar to look forward to future fun!  

I am in a marriage, among whose primary features seems to be exclusion.  
So I fill in the gap with paid sex, and try to be quite non-exclusive about it.  
I learned my lesson; I don't want another exclusive relationship.
