Hi
Im stealth at school, started at a new highschool in February. Im in new Zealand, so I think some of the laws are different, and I spoke with the dean and the admin dude and I use the bathroom in the sickbay, although that's annoying since its in the office where everyone is coming and going etc etc...
I would probably be able to use the bathrooms, but im pre-T or anything, plus the bathrooms here are sorta odd, theres about 5 small blocks throughout the school, small, I think 3 cubicles. Also some people in my year know im trans so it would be awkward if I met them in there.
When I start testosterone, ill end up using the guys rooms.
hope this helps, and good luck. Also, will you use a STP?
