They are unhappy in their current relationship and think that having sex with other people will fix it. It won’t.
Your current relationship has trust, honesty or major jealousy issues. If you can’t look your partner in the eye and tell him or her that you want to engage in sexual activity with someone else, the Lifestyle probably is not for you.
If only ONE of you thinks that being in the Lifestyle sounds like an intriguing idea, then you probably don’t want to go there. Don’t ever force, cajole, pressure, intimidate and insist that your partner try this. If you aren’t on the same page, it won’t work.
