Hey, shave that peach fuzz off

When I started noticing facial hair coming in I began shaving every other day. Now I get 5 o' clock shadow even if I've shaved that morning and by the third day it's gone from stubble to soft and long lol. I don't yet have a 'full pattern' yet, just bits of hair coming in, but since i've been shaving it hasn't slowed the growth or development down at all.
To satisfy personal interest I shaved one of my arm pits a little while ago (I was seeing if I still preferred the idea of having no hair under my arms and If I was just giving in to what society thought of as male, turns out I like the hair lol). That was about a month and a half ago, it's not as long as the other side yet but it's certainly coming in faster than when I was pre-T.
When my happy trail started coming in I didn't like it AT ALL so I shaved it off. When it came back in two days I decided i'd deal with it cause I wasn't going to shave it every day. I like it now, but the point is it grew back friggin fast!
It seems like all the hair that 'sprouted' as a result of T grows back much faster than places that simply got thicker. Ex: I have no doubt that if I shaved my legs they'd take a month to get back to where they are now, but If I go shave my belly of my face tomorrow morning, by Saturday it will almost all be back to the same length.
Peach fuzz is a feminine trait so I'd shave it off and keep shaving it off till it starts coming in dark and course. I personally hate the 'scruffy' look. I'd prefer to have a clean smooth shaven face than patches of hair, personally. But of course it's a preference thing. If you like what you've got now, keep it!
I can't recall if there's any scientific proof that shaving hair off makes it come back darker/more aggressive. I'm sure you could do some searching to find out. I doubt it makes much difference though.
