Uranus in the Composite 1st house:

Uranus is the planet of freedom and how it is expressed. No doubt this relationship came together very quickly and perhaps out of the blue, surprising not only each of you, but friends and family as well. Through this relationship you will learn a great deal about yourself, perhaps things you never even knew existed. One of the problems in this relationship is that someone may try to make you conform with society's wishes or with behavior that is "proper", which isn't going to happen, thus causing conflict.

You will be very restless and easily bored, wanting new experiences and needing continual activity so you won't feel trapped. You must give this relationship as much space and breathing room as possible if it is going to make it.

That's from the Composite Report

I'd add that people will see you and your partner as quirky.  An odd couple, but not in a bad way!
