I've been talking on the phone with this gal for a while. We agreed to exchange pics. I asked her what "type" of pics she wanted to see. She said she'd be open to anything I wanted to send. I took this to mean she was up for some naughty pics. So I took a couple and attached them to an email. But when I sent them, I selected a contact next to hers in my address book by mistake.

The gal the pics went to is just a friend; I don't know how she'll react. I was going to follow up with an email apologizing, but I don't know what to say. The pics were VERY graphic. Or do I say nothing?
