But that person isn't attracted to everyone of their gender, probably not even half, you still haven't given me a reasonable solution to the problem you've cooked up. What do you want done? Men who are openly gay to get their own showers? Women who are openly lesbian to get their own showers? (now we've got 4 seperate showering areas) What about bisexuals? What about people who aren't sure? Which bathroom/shower should they use? And how do you test for that? What about transgenders? Do they use the shower of their equipment or the shower of their chromosomes? If you're suggesting that all of these different groups need to be identified and forced to use a particular shower or bathroom, I think it would be easier just to say, everyone take your own shower.
