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.

Is polyamory better than monogamy?

Greater companionship, higher income, and ongoing sexual variety are often cited as advantages of polygamous relationships. Individuals who favor monogamy also tend to cite bonding, emotional intimacy, decreased worries of STDs, and other cases as reasons to opt for monogamy.
