As for many of us and this topic has been visited 100s of times.In NYC you may use the restroom of the gender you are expressing...most other places ie:vegas has the same policy. If you do use the ladies room which I do you need to remember to sit down while doing your business and exit as quickly as you can. Afterall women have been known to use mens rooms at venues.
California is also gender expression. I have used many and not had a problem. (Kohl's, Marie Calander's, K-Mart, and smaller venues.)
The crossdressing community is one that needs to stick together and continue to be there for each other for whatever one needs. We are always trying to improve the forum to better serve the crossdresser in all of us.
