I don't have many pictures of me either. Mainly because I realised at quite a young age I take a horrible picture.
The irony is I know I am all right looking, but I am the total opposite of photogenic.
My kids all take beautiful photos, (not just a proud mum, photographers love photographing them.)
So I dread family photos with a passion.
Thing is though my friends don't care, they will still take photos with me.
Just ask. They might think your just not interested.
