You may or may not have had this experience yet.  I've been lucky to have it 2x w/ GF's and not w/ any providers.  what i'm talking about is getting it in, and then having the squeeze put on so you don't get it back!... until she let's you go..

The first time this ever happened my eye's bugged out of my head and I blew it in 4 more strokes.  After that, it was heaven.  Some crazy muscular control there, it's really beyond belief.  The second time was w/ a GF that was an ex-provider.  Seemed that both were naturals.

I wanted to just see how many of us have had the experience... and if enough, maybe we can add that category to the ratings!  I can tell you (you listening ladies??) that'll close the deal for me quicker than anything else in making a choice.  

 Heard it was a common skill in thailand, and there are books out that purport to teach it.. Let's hear about snappers, and ladies who can 'snap'

in my experience this is a very commonly used skill among providers from those regions here or abroad. And I love it too.....
