I had a prince albert for almost a year, got it up to a 6 gauge. Liked the way it felt just walking around, something with the weight dangling off the end just did it for me. I had to take it out because I was in a place for several months where it really wasn't the best idea to have. I wasn't prepared to keep the hole from healing over, so I lost it.
My wife prefers me unpierced, and it really didn't do much for me or her sexually, but deep in the back of my mind there was something cool/exciting about it. Still think about getting another one at times.
I would just melt if my wife would get "something" pierced, but I don't think that's gonna happen either.
