yes, wait times can be very long and this is a surgery that requires a lot of planning. 6 months isn't even enough time to get your hair removal finished, generally I see recommendations to have 1 whole year of electrolysis and at least 3 full cycles of hair clearance. That alone is a huge amount of work and time - I had 1 hour electrolysis appointments once a week. When you add in the typical insurance requirements to have been on hormones under the supervision of a doctor for a year and the requirement to get two independent letters from psychologists, you are looking at a lot of appointments with endocrinologists, psychologists, and eventually with the surgery team. It's a lot - so start now if you think you might even possibly want it.
When I socially transitioned I practically promised myself I wouldn't get a vaginoplasty, I only wanted an orchi ... and that position was fully reversed after 6 months of estrogen. I wish I had taken the possibility of a vaginoplasty more seriously, and that I had started hair removal for that much earlier.
