I would use it, and be mildy amused while doing so.
I'm not into watersports, or even into that kind of humiliation ... not that anyone can humiliate porcelain objects at all. Now if women were brought in to act as urinals, maybe there would be grounds for objecting, but an image of a mouth (a man's? a woman's?) is nothing more than a cue to the imagination.
What I imagine is my own business.
It's like saying that a man who masturbates over a photograph is abusing the woman in the picture, or even over a hentai cartoon.
In my view, people do need to be considerate of other people's sensitivities, but imposing political correctness is a form of fascism. PC is a standard weapon in the armoury of militant femininsm, and I see it at work here. No woman has been harmed in the production of the urinals, or in their use. They are kept out of sight of women (with the possible exception of cleaners). Really, where's the problem?
This is just another excuse to make a fuss about nothing at all.
