Regarding some of the threads here I have avery good friend who is TG m>f and who is also lesbian as well and she was the first person I told because I could not hold back my secret any longer, as regards gay people not understanding/accepting us my friend has become an even closer friend as has her partner. It takes all sorts and as regards telling a gay cousin I see no problem here at all. You may find a greater degree of understanding, After all we are what we are but as someone once said "we just wired a bit different".
