My little guy as always peed like this.  He never squatted.  He thrusts his little hips forward and goes.  I think he learned it from his dad since he was raised with his mom and dad present.  I have puppy wipes, i think i got them at target, just like baby wipes, but are supposed to condition the hair and i just wipe him down with one.  Mine doesn't really pee on himself and i think your's won't in time.  I would guess it just means he's starting to become a man.  Are his little man bits starting to drop?  Also as far as licking and smelling I think most men would if they could.
