I have 2 male yorkies and thankfully have never even see their wee wee's!  The 10 year old has never had his out that I have seen and so far my 1 year old has not either.  Both are fixed.  The 10 year old only tries to hump the 1 year olds, but the girl puppy won't put up with it and makes him leave her alone and the male puppy just ignores him or walks away.     
I hope I never see their inner parts!  LOL.  I had a fox terrier growing up that would let his hang whenever he was excited though and it was not fun when I had friends over.
