This is the best word I've found to describe my situation.
Candaulism:
1, Refers to joy regarding the sexual activity of one's partner.
Commentary: Not to be confused with compersion, a feeling of joy, the opposite of jealousy, when a loved one invests in and takes pleasure from another romantic or sexual relationship.
2. A sexual practice or fantasy in which people expose their partner, or images of them, to other people for their voyeuristic pleasure.
3. A practice involving one person observing, often from concealment, two others having sexual relations.
4. Sexual arousal through watching two people having sex, particularly one's partner with another.
