Watch first, then decide
You can do all the Internet research you want, but you’re not going to really understand what it’s like to be in a swinging environment until you’ve been there. Your first time, it’s typically a good idea to just go and see how things unfold. Then, if it’s something you’re into, figure out how you fit in and go back. Make all your rules, and see where it goes from there.
You need to debrief
Kinda like those quarterly conference calls at the office where your entire team looks at what it's accomplished, what worked, and what didn’t, do the same with your partner after EVERY time you swing; the conversation will allow you to discuss the experience and figure out if rules need to be changed or added, or if there are different things you’d both like to try next time.
