Is it hot in here? No, it's just you two. Mmm, everyone's wanting some of what you have between you: sweaty, sticky, lovely lust.
Your connection got physical fast, simply because neither of you could resist each other. Opposites attract, so they say, and in your case they're absolutely right, with one's receptive energy meeting the other's force with explosive results. But there is (or should be) life outside the bedroom, and you two haven't had very much of it. It could be that one of you is using the other merely to slake a physical urge -- not a problem if both of you are in on the agreement, but nasty and painful if one of you is looking for love and the other just lust. One of you may also be very jealous and possessive of the other as well. The solution lies in extending your compatibility beyond the bedroom. Do you share interests in common? If not, better develop some soon. Talk about your values, your hopes, your dreams. Being close on one level does not an emotional connection make; you need to spend more time bonding and less time smooching.
