I've been to that museum. It is extremely bizzare with a bunch of real penises from all sorts of animals (and people) floating in jars. The facts on all the plaques are kinda fun, but many of the penises are in questionable state.
Also the museum was started by someone who was randomly gifted a whip made from a bulls penis. That kicked off a weird fascination and he started both collecting and being gifted more and more until he figured they might as well open a museum.
Last I was there, they even had a fantasy section for mythical beast penises. I only remember trolls and elves, but they had representations for each of the penises.
