Talk a LOT lol. Discuss mini things that trigger the jealousy feelings, like maybe your partner is lingering to long in a cuddling position and that doesn’t feel like it’s just sexual to you. Discuss kissing and both of you put time into picturing your partner passionately kissing someone else. Discuss what you think is okay and what you’re currently not comfortable with. The biggest things I’ve experienced to help with jealousy are detailed open communication at an extremely high level, and discussing things very openly with things both of you may feel some uncomfort with. You or your partner may be doing things to cause a feeling of jealousy and not even know it. You could be enjoying yourself while really bothering your partner. Try to cover all bases before going out to play. And constantly check on your partner. Take little breaks in the action and give some time and attention to your partner during play with others. And after you play, re-discuss how it went, what you were or weren’t comfortable with. And lean into change. You change and grow in lifestyle just like in anything else you do in life. This type of lifestyle needs the best communication levels you’ve ever had, which can be tough to start, but are w huge bonus to this lifestyle. Oh, also embrace your inner voyeur, and try to enjoy watching your partner with others. Make them your own personal porn star.. it’s hot and also helps ease away from the green eyed monster.
