Here's a bit of speculation from conversation with a friend today.  She's a bit younger than me, but is experiencing much of the same stuff I did earlier in life - I like to be with people, and I have a great time when I am.  However, I am terrible at initiating any of that contact.  What's worse is that without that contact, I get paranoid that friends are abandoning me.  It's a very vicious degenerative loop.  I've tried pretty hard lately to get better at it, and it's getting easier, but still awkward.  I find it interesting that the capability to initiate social contact is definitely distinct from ability to interact with others, and I'm curious how many other people have issues initiating like I do.
