You go into it with people who are comfortable with open relationships or who aren't entirely monogamous. I'd never got into one with people unless I was sure there wouldn't be any jealousy issues.

For myself, while I'm not exactly polygamous, I'm not entirely monogamous either. I've been in relationships with two different guys at the same time where they both knew about each other and were comfortable with the situation.

Drama and jealousy don't always happen.
