You actually only have to keep it covered for a few hours. After that, the only maintenance it needs is constant moisturizing. But yes, I imagine taking a shit might cause an infection for her. But maybe not. Who knows?
I once got one of those shock pictures that people text to their unsuspecting friends where a guy got shark teeth and eyes tattooed on his wang. It looked like the front of an A-10 Warthog. :eeew:
I think the worst part of that tattoo is not that it's on his dick, but that there is a girls name on it. I always think getting somebody's name put on you is asking for trouble. Kids is different, your kids will always be your kids, but getting a partner's name inked on you is almost inviting it to all go tits up.
George Carlin addressed that problem once. He suggested getting the person's name, but leaving some space just before or right above it so when the shit hits the fan you just get "fuck" tattooed on the blank spot.
