Am I flexible in what I’m looking for?

In general?  Yes.  What I’m looking for out of given relationships?  Perhaps less so.

I look for what fits me at that time.  If I’m looking for something more involved/entangled, and someone can only commit a day or two each month or every other month, that’s not going to work for me.  I tried it and it made me very unhappy because I wanted more time with them than they had to give and I reached the end of my flexibility.  

However, if I’m looking for something less involved or entangled (for whatever reason), then that kind of relationship works just fine for me.  Heck, I have one of those right now.  We talked at the very beginning of things and made it mutually clear that we were both a bit short on time and otherwise involved, but that it was worth seeing each other every once in awhile (has been panning out to 1-2 times per month so far, and that’s been great).
At this point in time, I’m not sure what I could do – I’m swamped in the high involvement/entanglement slots and very tentative about any other slots.  So, now I flirt.  And I have conversations.  And occasionally have makeout sessions.  Without the intent of it going anywhere.  Which is kind of nice.
