I've had tongue, lip, cartilage, industrial, and eyebrow piercings, and right now all I have are the industrial and cartilage piercing (industrial in right ear, single cartilage piercing in my right, with a ring.)
I like eyebrow piercings enough that I've had 3 of them; over time they always just work their way out or whatever. I lost my most recent eyebrow piercing just a month or so ago when I got an MRI; I had to take it out and afterwards, couldn't manage t get it back in, the piercing was so old.
I had my tongue barbell for years, and liked it, but eventually I was getting on a flight and realized one of the balls had come unscrewed and I'd swallowed it, so faced with the prospect of holding the bar in for a 6-hour flight, I took it out and tossed it in the trash. My boyfriend at the time admitted afterwards that he liked me better without it.
I had the lip ring for a few weeks, but it was healing slowly, was painful, got in the way of pretty much everything involving my mouth, and made a "clink" noise every time I put a glass to my mouth, which elicited giggles from everyone nearby. In the trash it went.
I like my industrial and cartilage piercings. I get compliments on them pretty regularly, and they don't get in the way of anything, they're not sensitive or painful, and they never need maintenance.
