+1 Florida V..... Riding in the rain really isn't a problem. I like a larger bubble around me and stay off the rear brake. If you haven't yet, invest in some rain gear. I have Nelson Rigg. It is very (A good thing!) and easy to get on and off. It is also relatively inexpensive for a quality product. We purchased ours at JC Whitney for about $75. We have used it numerous times and it has performed well.
Traction issues are not much different than with your car. Ride sanely and keep a safe distance and you will be fine. Oh, a windshield and full face helmet will significantly improve the quality of the ride during adverse conditions. Enjoy it and be sure to share the experience with your partner so she understands it is safe out there.
