i belive nomatter if your TS/TV/CD if you are curenly presenting as male and when i present as male like for me i am TS and i use the wheel chair bathroom or any one that unisex bathroom or the male bathroom(in desperation), and this should be the same for anyone presenting as male even(if like me) you are female if the curent appearance is male you must think of your own safety first, however if your TS/TV/CD and your curently presenting as female but for some reason you know you don't fully pass enough to enter the female bathroom then i sugest ONLY using the nutural/unisex bathrooms, and if you present as female(and pass) as either TS/CD/TV provided you do it just to be a girl and goto the bathroom to either fix make up, goto the toilet or just chat with your girls then your more than welcome in a female bathroom, if your in there to be preverted or anything then your in the wrong place, you wouldn't do the same thing in the male bathroom, that also goes for anyone who's TS and is presented as male in the male bathroom, have the same respect and don't be preverted to men either, the bathrooms are not the place for that.
this is how i feel and i am TS and i curently 95% of the time present as female and i do pass and i always use the female bathrooms when i need to goto the loo, and while i do fancy only women i am not in there to be preverted and anyother woman would be the same, it's something called respect of one's privacy and we all must obey this because otherwise your just a creep.
just remember be safe(enter as you pass best), be respectful and use the bathrooms what there ment to be used for, aslong as u do this then there is no problem using the bathroom.
