This is a fascinating question. I had a long post, but I'll boil it down to this. Whether I was in my 20s in the '70s or my 70s in the '20s, my frequency of sessions all turned out to be based on the following: time; cash; and guilt. (Oh guilt does still come in.) I've been active over a few decades, where I dropped out a several times for a few years. At my busiest, it would be six or eight times a year, depending upon the three reasons - PLUS who I was a regular with at the time or who I HAD to see at the time. With the Mistress I have served the past several years, who I have known off and on for at least a couple of decades, I do some work for her, we are friends (not romantic) outside of sessions and she sometimes gives me an AARP rate. LOL! When she retires so will I. So again, at my best, six or eight times a year.
