Off the top of my head:
Tingly/heating/numbing lubes - try them all!
Massages. Different types of massages. Even more different types.
Role play. Dressing up.
Mild bondage. Handcuffs, blindfold, whips, paddles...
Dildos, strap-ons, vibrators. Try them all, you'll never run out of new ones to try!
Oral. Hands. Knees, elbows, feet, moustache, nails, hair, try them all in every way you can possibly think. Worst case scenario you die laughing!
Look up what others in your situation do. Look up what lesbians and trans people do. There must be books and websites, hundreds of them.
Subscribe to OMGyes and work through the exercises together like homework!
Household objects. Paintbrush and water. Food. Showers, baths, a room with a view, the world is your oyster!
Always lots of communication, "yes, that feels good! No-ooo, don't think that's going to work for me..."
I'm quite jealous, really.
