Let me just start by giving a small time line.
Mid September I came out to some friends at work and tried to get a new nametag but was told I could not because my name was not legally changed. Was also told I could not use the men's room because I was still legally female.
Late December I had my name change legalized.
First week of January I got my SS card and new driver's license so I got my new nametag at work and am now fully out as FTM go by male pronouns, male name everything, but the thing is I still use the women's. A friend online told me that I needed to go to the store manager and not ask but tell them this is how it is going to be and if you have questions I can answer them or try to and here is my lawyer's name if you would like to ask him anything. Ideally there would be a unisex bathroom at my workplace but there is not. I'm not comfortable going to the women's but I'm nervous to go to the men's. I'm even more nervous to try to broach the subject with my workplace.
Maybe I should not even try to ask/tell them anything and just start using the men's and if they say something about it tell them I just assumed that now that I was presenting/living totally male I needed to use the men's room and should actually use it to save myself and coworker's discomfort.
I would really like advice or stories of your experiences with this topic.
