People can have sexual and romantic relationships with one or multiple people, while others are not attracted to, or interested in, having a sexual or romantic relationship with other people at all. Here we describe some common relationship styles.
Monogamy: Having a romantic or sexual relationship with only one person at a time. Generally, this means committing to one person emotionally, romantically and sexually.
Non-Monogamy: Having more than one romantic or sexual relationship at the same time. These relationships may be open, where partners can seek out new relationships with other people, or closed, where the relationship is limited to a specific group of people.
While these approaches may not work for everyone, they are both valid ways to create relationships if all involved are fully aware of which type of relationship they are joining.
The type of relationship a person wants can change over time. Regular communication with partners to discuss relationship preferences can be helpful.
