Hi SassyK - M & P definitely needs to sit on one of those soap dishes that has the grooves in the bottom so that it doesn't turn into soap soup! I've got an inexpensive one from Spotlight and sat it on the rack in the shower. If you let it drain between uses it lasts almost as long as the commercial soaps!
