Set Clear Boundaries
Before you head off to meet up with other swinging couples in person, it's wise to have a very open, honest conversation with your partner and set some boundaries. While it may be something you've talked about together before, letting them know how you feel on the day, what you're up for and what's off the table can help you both to feel calm and confident, and reduce any nerves or uncertainties that you may have.
Communication with your partner is key to enjoying the whole experience. Discussing what you're willing to do and not do also means your partner can look out for you and read the signs if you're not happy with something later on.
If you're already talking with other swinging couples, you should also let them know where your boundaries are. Doing this before you meet up can help settle the nerves and be easier to share ahead of time, so everyone has the same expectations and is on the same page.
