So what relationship structure do you want? For those that may get confused by the terms: Monogamy: a relationship where both partners are only in love and have sex with each other. Monogamish: a mostly monogamous relationship, where both partners have sex with each other most of the time, but occasionally have threesomes or allow to have sex with other people on special occasions like business trips. Open relationship: a relationship where both partners are emotionally exclusive but allow each other to have sex with other people as long as there's no emotional involvement. Polyamory: romantic and sexual relationships with multiple people with the consent and knowledge of everyone involved.
