You kind of need to look at BOTH sides of the family for these things. I am not sure re: facial hair. Male pattern baldness is on the X chromosome, but then males have an X chromosome, so...
It's going to take awhile to grow the facial hair. I've seen older guys grow it pretty fast but the young guys. Think about that 20 year olds tend not to have real much facial hair. OTOH, you're going to have an easy time being read as male, though guessing you might look younger (tends to be a common thing).
For pictures you can easily set up a free imgur acct. It just wants a name, email, and password. This allows you to post onto susan's. I don't really know why it doesn't allow you to do this directly but oh well, it's easy.
