The short answer is yes, for me it is a turnoff.
There is a valid rationale for it however that does not mean that I am living in a dream world nor does it mean that I do not appreciate or understand or support what an SP does for a living. I know that they see lots of clients and I enjoy writing reccos so that they can perhaps be more successful and more men will be in contact with them.
I know that men and women are different in their ability to "recover." I for one REALLY wish it were not that way, but an orgasm for me means that it is time to relax, cuddle, talk. I am not going to be immediately ready to go again.
Women may have that biological advantage, but, and this may be ignorance on my part, I really would wonder how a woman would be able to have appointments back to back and still show the interest and enthusiasm and sincerity that I have been so fortunate to have been on the receiving end of in all of my encounters. It is the interest, enthusiasm and sincerity that I love.
If we go one step farther, and I see ads that say they have appointments available for 2, 4, 6, 8, and 10 then my head says that surely if I am one of those later appointments, then I am not going to get the experience that I so enjoy.
I may be totally wrong on this.
Finally, I have not met an SP that I did not like. I know that from my personal perspective, I would like them to be financially successful while at the same time give themselves an opportunity to have a working routine that leaves them room for R&R, room to maintain their physical and mental health, and room to make every encounter that they are a part of an awesome experience not only for the client but for themselves as well.
I may have got off of the thread a bit but a large part of my answer is based on my concern for them.
