If you seriously look like a woman, you can go in the woman's bathroom and guess what, nobody will loving say stuff.
If you seriously look like a man, you can go in the Men's bathroom and guess what, nobody will loving say stuff.
But quite honestly, there shouldn't be gender specific bathrooms to begin with.
There should be- wait for it- loving NORMAL BATHROOMS! Where like, you go in, close a door, drop a turd, and leave.
