Don’t choose the wrong partner.
You may be curious about a sexual rival–that person your mate dated before, or during your own relationship–but bringing that person into your threesome fantasy may backfire. Your lover will automatically go into comparison mode, and he will have a blast, but you may be so self-conscious that you’ll freeze up. Sometimes you’ll play, sometimes you’ll watch, take your cues from the flow of the evening, and how you feel about what’s going on.
