That's excellent to hear. Experiences like that definitely have an amazing effect on one's wellbeing. So congratulations!
When I wasn't passing and had never passed before, I was out to my boyfriend and he always used male pronouns for me. It was natural coming from him, and he reassured me often that he can only ever see me as a guy. Even when the rest of my life was crap and I was a girl to 99% of those around me, that was pure joy, and it kept me going.
