Quote From: mdearest  
I am in the process of a divorce, but am horny to be quite honest. I don't like just sleeping around and my stbx husband had indicated that he is also horny but is not wanting to sleep with his current lady friend until we are officially divorced ... should we sleep together? If we both go into it knowing that it won't change the overall situation, then we are just two consenting adults with a history, right?  
No do not sleep together
You need a fresh start and to get on with your life
This will only prolong the pain and suffering divorce brings
GO OUT and find another
Sleeping together will do you no good. It will take up time that you could be with someone else
