This scenario is typically referred to as polyamory.
Polyamory is a type of relationship where individuals have multiple romantic and/or sexual partners with the knowledge and consent of all partners involved. It's important to note that polyamory is not the same as cheating or having an affair.
Here are some key aspects of polyamory:
- Open communication: All partners are aware of the relationships and actively communicate about their needs and boundaries.
- Consent and respect: All partners freely consent to the arrangement and respect each other's choices.
- Variety of structures: Polyamorous relationships can take many forms, from having two primary partners to having multiple partners with different levels of commitment.
While polyamory is becoming more widely accepted, it's still a relatively new concept for many people. It's crucial to approach polyamorous relationships with honesty, open communication, and a willingness to learn and grow.
