How to Have an Open Relationship

Exploring open relationships can change our assumptions about intimacy and empowerment, and give excitement to a world otherwise determined by the limits of the present culture.

Separating commitment from sex opens possibilities for different types of long-term or committed relationships and redefines family. There are many people in open relationships who choose to have children. There are nonmonogamous couples, some of whom are married, who don’t live together. Or there are couples who have been together for decades who don’t have sex with each other any more (and do have sex with others), but still maintain their commitment and intimacy. Being in open relationships takes a lot of emotional energy. But the self-awareness I bring to each relationship makes me feel authentic.

    Technology & Innovation
    • Spectroscopy provides a non-invasive way to study the chemical composition of matter.
    • These techniques analyze the unique ways light interacts with certain materials.
    • If spectrometers become a common feature of smartphones, it could someday potentially allow anyone to identify pathogens, detect impurities in food, and verify the authenticity of valuable minerals.
