It all depends...
I too suffer from the same affliction - i have found with experience that the best thing to do is find a couple of ladies you like - then book longer sessions. I usually book an hour or an hour and a half.
My PE is such that after becoming undressed i will cum very quickly - massage doesnt work - i can cum lying on my belly which is a waste and having a tom hank is no preparation for the real deal.
Most ladies (especially if you have been before) dont care how many times you cum - I have managed 4 in a session but usually its 2! Its actually a lot of fun getting restarted for both with time for a chat - never tried edging but will hopefully soon!
