Not gonna lie, but, I'm very much looking forward to hair growth once on T (whenever that might happen).
Facial hair and a "happy trail" primarily...I don't want back hair, and don't necessarily care if I get chest hair and could go either way on that one. I really hope I get a "happy trail" -- my younger brother has one, though my pops and older brother are quite a bit hairier than he is.
I'm hoping I'll get good growth and pretty early on. I already have a few that have been growing for a while just below and to the right of my chin, and then a bit of a 'stache (primarily the ends) that is kind of prominent but doesn't really grow. My brothers have gone through or are going through phases of patchy growth, but my pops has a fairly long, thick beard and has had it since he was in high school.
I'd probably rock the stubble (with thicker sideburns) primarily and occasionally do something more with it. I'm almost hoping for the happy trail a bit more than the facial hair, but largely they're about tied.
