Ok, so I know I don't have a penis (I looked), but maybe that means I can be more objective about the circumcision issue. Also, as a consequence of my gender and heterosexual nature I've probably been in contact with more penises than most of you in this thread (unless you're gay, of course). So read if you care for a female's perspective.
1. Cleanliness
Circumcised penises tend to be cleaner and, er, smell nicer. Uncircumcised does not necessarily mean dirty though.
2. Doing the deed
Prefer uncircumcised. Feels different. Better. Easier. Nicer.
3. "Hard and dry"?
Yes, circumcised tends to be noticably drier and the skin harder, and from what I can tell, less sensitive.
All in all, imo, uncircumcised is better, but it's not really a big issue to me. I'd compare it to having small tatoos- imo, better without, but if you've got then so be it.
If I ever have kids, I would choose for them not to be circumcised, even though I come from a family where boys are circumcised.
