I like eyebrow, ear, and bellybutton piercings, and certain nose piercings. I personally don't have any though. I used to have my ears pierced a long time ago but I had problems with them healing and eventually decided to just let the piercings close back up.
I like to see women with their nipples pierced. Not for those who ever want to breast feed though. I have had my eyebrow pierced though it ripped out. Industrials look good as well as some from the Helix to the lobe.
I have a vertical labret & I think it looks super cute on many people. I know a lot of girl pierce their navels (myself included) but I actually removed it because it prevented me from effectively exercising/snowboarding. On guys I really love ear piercing(s). Just on one ear. Or a tattoo. Ahhhhh :D
