This is indeed a tricky subject. I agree with most though, use the one you present as and make sure your feet do face the right way when you go. I use the women's when dressed but I will confess that I am still nervous when I go when there are other women already in there or when they come in. It took me awhile to get used to using the men's room also. I just need to start using the women's more often to get used to it. At the salon I go to, I politely asked what restroom to use and they said for me to use what one I feel comfortable in.
