I know there is a type of condom with chemicals that can numb your dick so that you will not come in seconds.  It's weird that I have premature ejaculation only when having sex with providers.  Maybe I m too excited with providers.   Any suggestion for my PE problem? Thanks a lot "

Despite the advertising, with me they take away sensation and it will take for friggin' ever to actually orgasm.  Okay, not really, but it was easily double my normal time.  Your results may vary.  But for me they damn near knocked out all sensation - with eyes closed I couldn't have told you if anything was touching my prick.  At the end we were both wrung out just trying to reach my finish line, and it started to feel like work.

Jerk off before you meet them. Seriously. Get the easy one out first. Common practice.

They don't pick those guys for their looks.

Yes, even Ben Stiller uses that technique.  

he says out loud  

Now that's some funny S**T!!  Thanks ...

I like your thinking!!!!

not every lady allow round two.  sometime I couldn't get it up again after exhausted

The great thing about the search feature is that you it makes your decisions easier if the provider won't allow for another pop.  

First things first is to get comfortable with your partner.  
Diaphragmatic breathing. Concentrate on your stomach moving up and down.
Stop thinking about your orgasm.
Be in the moment, feel the pleasure and pay attention to it from a bodily holistic perspective, not just your unit. Don't think of baseball, I certainly do not want to think about Sammy Sosa while coming, and it will make you go faster.
Be relaxed, but do not relax. In other words, don't just lay there expecting something to happen, but try to relax and be excited about things.
