Preferences are a personal thing, just like some men are turned off by women with body hair while some men prefer women to keep it!
You'll probably encounter women who have different preferences regarding circumcision. I know a couple of girls who say they prefer it, that it looks better and is cleaner. Personally I have a strong preference for uncircumcised, just because I love playing with the foreskin and just don't enjoy playing with a circumcised one as much. However, it isn't the be all and end all - if you are into someone, you tend to be into all bits of them too, whatever those bits look like!
