Although you will have different capabilties---stamina, feel for the wind---I believe the goal is to get both partners up to the same level of seamanship, which can be learned over time.
Recommend you both read Suzanne Giesemann's excellent book "It's Your Boat Too" (It's Your Boat Too: A Womans Guide ... - Google Book Search
) and her excellent monthly column in Blue Water Sailing magazine.
Ty and Suzanne Giesemann are both retired Navy (Ty a Captain and Suzanne a Commander) and both have USCG 100 ton licenses. They were my neighbors in the DC area just prior to retirement and they know their stuff.
Enjoy the learning process and remember that you are partners in the adventure.
