Sex, sex and more sex. Scorpios are motivated by the intense passionate power play of it all. It is not a bad thing to play a bit of a mind game with them, if you are prepared for the volcanic finish. Entice them with faraway travel and exotic treats. If that doesn't work, give them a kick in the patoot and wait until they come to you.
Goats measure their own worth by what society dictates.
If you find them more than a little closeted, give them the benefit of the doubt and blame it on their astrological karma. They need to feel important because they really have such a low self image. Listen to their advice and make them believe you will follow it. It may seem that ice water runs through the veins of these folks. It's not really true.
