My son (19) asked me if I was gay. I said no, I don't think so. My youngest daughter (17) seems fine with it. I don't present as female when with them, but I am usually dressed in women's jeans & shirts. So far, they seem fine with it. They know I have a very strong feminine side and I am trying to learn more about myself.
I have an older GG confidant at work, she is very cool. I expect that little by little she'll let my secret out, and then it won't be a secret anymore. I dress 90% fem at work anyway, and I've quit pretending to be all man. So there is probably not much secret left there anyhow.
