Uhhhhhhh, no? Blade is blade, clean it with alcohol between uses if you’re that worried.

I’ve never heard of anyone not using the same razor everywhere.

Maybeeeeeeeee they’ll have a separate one for their face and I could understand that, but that’s about it.

think the logic is that trans femme people are more likely than most to need to shave all of those areas. Traditionally cis men having arm and leg hair is acceptable while most shave at least some part of their beard, and many cis women do not need to shave their face but are expected to have smooth arms and legs. Trans men, if on T, I presume would be in the same category as cis men as T will encourage that hair growth.

I don’t. The same razor handles everything. Of course, I have disposable blades, so I get a fresh start every week or two.

I think it’s preference, but people tend to use electric Shavers for sensitive areas, and use waxing and razors for the body, because it hurts less on thicker skin and it’s worse if you nick yourself with a manual razor when shaving thinner skin.
