Laser and beard removal can be done at any time, but better to start asap, as it takes forever. I am open about doing that and nobody thinks it's for transitioning. Find a local trans support group and go and learn. Learn about doctors, health insurance, what others gotchas are. Usually any support group is on the dl, so you should not be outed.
Congrats, BTW, I accepted myself at 46 too. It gets better. Welcome to Susan's too. You have come to the right place.
