Obsessed? Speaking strictly for myself, I have a preference for foreskin on the dicks I suck. It makes the entire exercise more interesting and it excites me tremendously.

I remember the first uncut dick I ever saw in high school PE. It belonged to a muscular Latino named Angel, on whom I had a little unrequited crush. Seeing his uncut dick between his legs just cemented the whole deal for me.

When I lived in France it was like an all-you-can eat buffet 24/7. I was in heaven.

But getting back to the original question: it's been my experience after 30 years having sex with other men that the vast majority is more fixated on size than whether or not said penis is intact, and that if there is a majority preference in the US it's for cut, not uncut cock. In all my experience, I've only met one guy who rejected me for being cut, but he was an anti-American bigot with much bigger issues anyway.
