I had a beard most of my adult life, but when I shaved as a guy, I used an electric. An electric has almost zero chance of nicking the skin. It doesn't get as close as a bladed razor, but with peach fuzz, no one will notice.
Once your beard thickens up, you may find that an electric doesn't get close enough to hide a shadow, and you might have to switch to a bladed razor if you are still closeted at work. The more blades in a razor, the closer the shave for the same amount of pressure and effort. So I would recommend a three, four or five bladed razor to get a close shave in one or two passes.
My skin is quite thin and fragile now (a year and a half on MTF HRT), and I use a three-bladed razor.
