I'd rather get a PA again than nipples again. Only the ampallang hurt worse than nipples.
As for wands, that's a big step up from just the PA. A lot of guys find that even a 2-3" wand is intolerably irritating, and some can't even stand the discomfort of putting it in. Me personally, I could wear one for short periods, but couldn't "do" anything with it in.
