I'm an advocate of, if you're coming out, put it in the same terms/language/verbiage that your friends or family can understand. It's really tough for someone who hasn't walked in our heels (see what I did there?) to understand what we're going through, so I feel it's often better to explain it to them in a manner that they can relate to.
When I came out to my friends, I told them that I wasn't going to do this 24/7 and that it was just a form of self-expression or, better yet, just clothes. Since my friends were gamers, I told them that something like this is similar to playing as a female in role playing video games we've played.
They accepted it for what it is because they related something we've all done at some point to what I was doing. Later down the line, when they got used to it, they finally asked me why I do it and what it does for me. It was at that point that I told them my thoughts and feelings about the whole thing and they got even more curious and more understanding of the situation.
