Been said many ways in the past, However, "How do you Really Measure your success in a encounter"?  
 Just a few thoughts below.  
   
 1) Only by a number scale 1-10 - Haven't thought in those terms.
 2)Number of COC - ??
 3) The wow factor - If that means her looks, well looks DO affect my attractedness.
 4) Amount of phyical enjoyment for yourself or your date - If we are both 'spent' after our encounters then that's a good sign.
 5) Amount of emotional enjoyment - This is something that developes over time. I have a provider that I have been seeing for more than 8yrs. and we seem to really connect emotionally, so much so that she allows me special access. We have become good friends.
 6) Chemisty and connection - This goes with #5. Chemistry can happen on the very first visit and can develope in time. I only see providers that I have a certain chemistry with. That has only happend with 2 of them over the years.
 7) Wild and raw factor. This is why I see my second provider. She has that wild side I enjoy every now and then.
 8) Repeat factor- if some of the above happen, then I will repeat.
 9)Romantic and sensual side - My long-time provider really brings this to the table. That's why she is my ATF.
 10) Beauty and body factor - These have to be there to start things off for me. If I don't have an attraction, then I will not make a move.
   
 Any feedback would be appreciated!
