Well Awesome, I am confused (not a first). You are either in the most "cut" part of the UK or you have had very few experiences. Statistically based on a map depiction by WHO, less than 20% of men in the UK are circumcised. So I think that if you desire to play the field you may have to modify your criteria or your outlook.
Also just like every circumcised cock, no two uncircumcised cocks look the same. Speaking for myself when I am erect, it is impossible for my skin to come back down over the glans, and several women have thought I was cut, until I went flaccid (meaning dick went back to sleep).
I seriously doubt that if you really are looking for something in the 9" range and the guy that showed up at your door or in your bed was driving a BMW, had a hefty bank account, six pack abs, pretty boy looks (think Becks or Pitt); that you would kick him out for having a foreskin.
And yes, I am not hitting on you, but I am lecturing you like I would my daughter. So loosen up, experiment and enjoy life, you never know what you might be missing.
