Sex with a uncircumsized man to me is great. As for head I have also found that a uncircumsized penis really isn't that much different than a circumsized one. I have found that a little suck and swirl like licking ice cream seems to do great. What I do is grab the shaft,twisting up and down,start the suck (pop)then the swirl. Also popping the suck like your pulling a lolly pop out of your mouth drives my man crazy. Try it and let me know how it turn out for you
