Eco-Friendly sexual relations or sex practices.
Some ways Jack and Jill practice Green Sex:
Instead of driving to the movies and dinner, Jack and Jill biked to the farmers market for food, and took a walk in the park.
Jack gave Jill locally grown, pesticide free, and fair trade flowers for valentines.
During sex, Jack and Jill used only all natural lube with non harmful chemicals that don't disrupt the balance of the environment.
