I've been putting a large sports-size band-aid (1"x 3") over the area where the electrologist will work. All the growth is underneath the band-aid. It just looks like I've been injured. No one knows there are whiskers underneath.
If someone asks me who doesn't know me asks, I can make up a story. People who know me and know I'm trans can know the truth. But I can show my face in public without being unpassable.
