It's annoying getting EAS, even mildly, as it interferes with an otherwise great GFE punt. I'm not smitten, I have felt the same way toward close family friends to give an idea of what I'm on about. If my EAS starts getting out of hand I have some remedies.
I do some searching on SAAFE and read the threads on needy, pushy clients as though it's the favored prossie talking to me.
I also look at her old reviews. Knowing that she did anal followed by CIM without missing a drop, all for less than what she charges now, has a sobering effect.
In the punt, when kissing, watch her eyes. Chances are she'll be looking around bored? Maybe checking the time.
Try to keep chats non personal. Sometimes I give too much of my personal life away (under direct questioning from the prossie). The prossies life is a well rehearsed fantasy for yet another punter. This last point is the best one for me to remember, by all means have a great time, good chats etc, but only for the paid time and take it all with a pinch of salt.
Doing the above helps me alot, I'm trying to keep sex and punting in context as well. It can be time consuming so having some other hobbies and interests will help keep things in focus.
Best of all are the threads on here. It's like having a load of mates at the pub, giving a good bollocking for being weak.
