Facebook just released new share/connect functionality in the form of Send Button. The send button enables your site visitors to send your content directly to their friends as a private message. Unlike the share and like buttons, which post to a users wall, the send message may be more effective as it targets individuals or Groups. Presumably the recipients would have more interest in the content, otherwise why would someone send directly to them?
With the facebook send button, you are able to quickly and easy share private content without having to look up email addresses. The button auto suggests your facebook friends and groups.

Or, if you are more a do-it-yourselfer, here is a little snippet of code that you can add directly to your WordPress Theme. This uses the get_permalink code so add this code to your loop so that each post can be shared with the send button.
<div id="fb-root"></div>
<script src="https://connect.facebook.net/en_US/all.js#appId=APP_ID&xfbml=1"></script>
<fb:send href="<?php echo urlencode(get_permalink($post->ID)); ?>" font="arial"></fb:send>
