All three! Of course, I love to wear, that goes without saying. I love flooding my diaper and filling it up with as much peepee as it'll hold, but I really love having a big poopy squishy messy diaper. If it didn't smell so bad (I really need to look into those internal deodorant pills), I'd do it all the time. As it is, I do it multiple times a week.
Even as a kid, I loved to wet my underwear, but the real fun was always after the wetting, when the big squishy mess came.
