Does circumcision affect sex?

I tried to make this a poll but couldn't write enough in the spots available. So this is what I'm wondering, and it's not about if we do it to are childern when they are born. What I want to know is, Is an circumcised man better in bed because all the friction is there? Or is an uncircumcised man better because of the extra skin and lasting longer? This question can only be answered when someone has had both experiences.

How I got to this question. My very first was uncircumcised and then, what felt like forever, he would finally get off. For me I didn't realize how much I was missing out on from the friction of the skin being taken off until I slept with my second person, but they were obviously circumcised and didn't last long, and everyone else since then except for the first. I did end up sleeping with my very first 15 years after we split for a quick fling and again I found myself missing friction but being more sexaully satisfied because he lasted longer.

So I wonder if circumcision affects sex?
