Congratulations! I went through something similar about 6 months ago and I know the feeling. I just didn't want to hide it from her anymore. She turned out to be OK with it. I think this kind of thing usually goes better for younger people (not to say that it doesn't blow up on someone younger). My advice is just to take it slowly. I've heard of people that come out to their SO and then start dressing constantly that drives them away. Think of it like easing into a swimming pool. :P For me, having someone that knows about my dressing was a big step towards self acceptance and helped me progress faster learning how to properly apply make up.
