Why would this beautiful woman use the men's restroom?
If a woman feels uncomfortable sharing a restroom with Laverne Cox, then get out and let Ms. Cox do her business. Besides, haven't most of us lived in a dorm? In college I shared bathrooms with girls, boys, trans women and trans men, all in varying states of drunkenness and sobriety and exam-based terror at all hours of the day and night. It threw me off for about two days, then I got over it. Women are in WAY more danger of being molested or raped walking down the street at night alone than we are peeing in a stall next to Ms Cox. In fact, I'm betting you're 99.95% safe with Ms. Cox. I simply ask her to be courteous and flush.
