I would suggest you do a little research on they “lifestyle” before taking part. It’s a good idea the to get a good understanding of the type or rules or etiquette different groups or couples follow. I photograph a lot of swingers in the lifestyle and participate in several “swinging” groups on Facebook. Each lifestyle group varies a bit in how the conduct themselves. It’s important to find a group that is welcoming and operates in a way you and your hubby are comfortable with.
You should be clear with your husband what you are both looking to get out of this experience. Determine whether you are interested in full swap or just bringing another person into your lives for “playtime”. It can be a lot of fun and with the right type of interactions very fulfilling but a single bad experience could be very damaging. I think going in edjucated can make a huge difference.
Ok that’s my perspective. I hope this is helpful.
