Some polyamorous people get jealous, some dont. Just as some people in monogamous relationships get jealous and others dont.
It is probably safe to say that jealousy does come up for most people at some point. The difference between polyamory and possessive monogamy, is that people who are polyamorous dont consider jealousy as proof of love (if you really loved me, youd be jealous). Instead they see jealousy as a difficult reaction that needs to be thought about, talked about, and dealt with in some way.
Being polyamorous doesnt mean you cant feel jealousy, nor does it mean you have to deal with jealousy on your own. In a polyamorous relationship you and your partner(s) will talk about what happens when one, some, or all of you feel jealous. It may be an indication that someone is feeling left out, and that can be addressed. It may be an indication that there isnt enough communication, which can also be addressed.
It is very important for people in polyamorous relationships to be aware of their jealousy and not to minimize it or ignore it.
