The sex is just an added benefit. :

....and this post is a good example of why I love being naked with you!!!  You have the keys to my heart, you amazing woman!!!!

you change the conversation.  with you, because of you it is not about a score or the money.  you are so well thought of and highly regarded that others will learn from you and learn to share themselves with others.  

I have referenced bob Dylan before to describe Trinity, this one is from Harry Chapin;

I'm a sad sack Sir Galahad
who's sword's around his knees
with a Grail no longer holy
and a prayer that's saying please

your the one who listens
when I need a little light
now I'm lost inside the ruble
so could I come on over  
with my heart in my hands
and place it on your pillow
like a rusty old tin can

could you once again
be the friend that you've always been
and take me in  
please take me in

ladies, if you love your clients like Trinity does your life will reward you with more than money.  If your clients do not love you the way we love her, tell them to go away
if you are kind you deserve only kindness, nothing less.

To find someone you trust enough to know the real you.
