You'll have an very affectionate friendship and you'll enjoy connecting with each other. Even though you're just friends, there may be a strong component of sexual attraction between you. It won't all be smooth as cream, though -- you'll irritate each other sometimes, and your friend, especially, might even antagonize you from time to time with coarse or crude behavior.
They'll have an exciting and sometimes irritating influence on you, but you'll have a calming influence on them. You'll know how to talk them down when they get worked up; you'll often take different but complementary approaches to a problem. That means you'll bring your own strengths to any given situation. If you work together as a team, you'll be stronger than each of you would be on your own.
