Some people are in relationships with multiple partners at the same time. Sometimes these relationships are mostly about sex (casual sex contact), but the relationship can also be based on emotional attachment.
If you have unprotected sexual contacts with different partners, you may run a higher risk of STIs. Use a condom to protect yourself, your partner and other people.
After some time, a relationship with multiple partners can become too difficult, for example because of secrecy and jealousy.
In Norge it is forbidden by law to be married to more than 1 person at the same time.
