Physical attraction, and I assume that is what you are referring to when you say "two in particular that I am still attracted to", is important, but only part of what draws you to the dance.  If there was no connection beyond that, I would accept that as part of life's mystery and move on.  That is, unless you believe there is a particular reason or circumstance that may have affected the visit, which may be different on a second visit.  Only you or the lady in question can answer that.  

Sometimes that is the way it goes in spite of everyone's best intentions.  You could ask her if she feels the same and if it is something you could work out, which I would before scheduling a second visit.  Or you could just move on.  You have had many successful dates and there are many choices, so why chance repeating a bad one?

is that I believe everyone has a bad day every so often so you may want to give them a second chance, especially if its already been on your mind. Theres obviously something there thats keeping you interested. I also think its a wise idea to be upfront with them before you schedule another appointment and tell the provider some of your concerns, likes, dislikes and she how she responds. Remember you CAN'T always go by ratings either.

That is a hard one.  I have seen the connection evaporate sometimes in later dates.  It happens to both sides.  Maybe she had a bad day, maybe you had a bad day.  Milage varies for each of us, this whole dance is seen so differently.  Mostly everything ends up being in our heads,  actually the big one.  She said something or did something that you percieved as being a non connecting thing and it stuck.  I have gone back a couple of times and it still didnt work for me.  But then she was dealing with my fugly self so lets not blame her.  I am happy she tried and will kick no dust her way.
