Today I went out as Katie to see my cousin and come out as Genderfluid. He didn't realise who I was until I told him! He recently came out as gay to our family so I decided he might be able to help me and i would come out to him first. He was completely cool with it, just how I hoped and expected. He even revealed to me he occasionally crossdresses so things just got better! So now comes the hard bit, the rest of my family...
Congrats You could ask him to be at your side when you tell the rest of your family, it would perhaps make things easier? But in any case, nice job! (!)
