Personally, I only disclose my status before intimacy happens. By that I mean french kissing or sex.
It's a new role that you're learning and flirting is all part of it. To be seen as feminine and attractive is a good thing, I've only been full time for a short time and always welcome behaviour like this, because to be honest, most encounters stay just like this- one off encounters that bring a smile to your face, but are all part of the process of finding your new place in our world. It really is a second puberty we're going through.
I'm not a believer in restricting one's life until everything is perfect. I mean, when's that ever gunna happen?
Stay Safe,
OXOXO
