Forget the fact that they’re not the same species. They’re not even in the same Taxonomic class. Bowser, a turtle, is bound to want to fertilize her eggs externally. Peach, a mammal, probably won’t be into that whole scene. Then again, given Bowser’s size relative to the Princess, it might be better for her health to keep things external (especially considering that Bowser and his ilk tend to have spikes in odd places.)

This is apparently a screen from Super Paper Mario which comes out in April for the Nintendo Wii.
