Is a polygnyous relationship possible?

I'm a 20 y/o married and have recently been thinking about the idea of polygyny specifically. (Not any other kind of polygamous relationship) In my head, between 2 adults with good mental health, similar interests, and good vibes I feel like it would be a dream land. Thinking as far as a long term committed relationship, it would be so much love between 3 people I don't know it makes me feel warm inside. Through the tough times I think it would be so good to have another person help care for and love in the time of need. Raising kids is already hard enough with 2 people but 3 people would make things so much easier. Do any females think this could work? Any guys feel they can handle this kind of relationship?
