It seems I missed your post : (
eggy, eggy, eggy, I'd never get offended by you. I was being sarcastic, even though I have no recollection of making these posts ... Just like when I say Rev is totally insane for seeing the same MPA so many times. Did I actually say that ? Well, he is and so am I , but I'm weak when it comes to certain girls ...
In all seriousness, I've actually seen another MPA more times than Jade. At least 20 times; although not all in a row, there were many consecutive sessions. I think at that time I went back and forth between just her and one other MPA, who to date I've seen abt 7 times and I intend to see again. I do tend to find an MPA and stick with her as long as things are still creative, spontaneous and fun.
It's when sessions become too predictable and the same that I tend to move on, but if $ weren't a factor I would very likely still keep seeing them, while keeping an eye out for a potential new hidden gem to fool around with on the side.
With the exception of Jade, I tend to like the less well known MPA's, who eventually tend to become "well known" ... I'm so underground, maaaan.
Although I think that 3 sessions is generally when I can tell if the fun has even more creative potential, I don't think there is a magic number where things become somewhat "mundane". It depends on the individual MPA. I will say, that seeing the same MPA too frequently may dim any spark more quickly.
