We don't have a videocamera, but my digital cam has a little video thingy that does the job (bad resolution, but it works). So we've done lots of little self-shot videos... I thought everyone did it?
I know for a fact that those vids got my bf through the 2.5 month separation we had this summer... and I enjoy watching them, too. Wish we had a 3rd person to film sometimes, but someone who wouldn't be jacking off the whole time.
