My personal experience is that uncircumcised guys have MUCH more sensitive glans and have much bigger prgasms and easier too. I LOVE uncircumcised men because I love to chew on the foreskin, stick my tongue inside it and tease them, slip it forward over my tongue, and stroking one is
so much more sensual and satisfying, especially when they cum in your mouth!! The added sensitivity does make it more INTENSE when they orgasm, and so much so that my husband prefers not to cum this way orally and I get very aggressive with my tongue and teeth when a guy comes in my mouth, many of my uncircumcised lovers have been the same way.
