Whats the short answer? In short, polyamory is the act of having intimate relationships with more than one person at the same time. A polyamorous person might have or might be open to having multiple romantic partners. Polygamy, on the other hand, involves being married to multiple partners.
How does a poly marriage work?
Polygamy is being married to more than one person at the same time, whereas polyamory involves both married partners having the freedom to have relationships outside their primary relationship. Polyamory is not a sexual orientation, but more of a lifestyle choice.
Can you have a polyamorous marriage?
Polyamory is not for anyone who is jealous of other people moving in on their husband or wife. It often works as a marriage alternative for couples who have been together for a while and are on the verge of a divorce due to sexual dissatisfaction, or couples who want to explore something new.
