Congratulations! You have clearly described a common pathway in the LS.
From the outside looking in (aka vanillas, interesteds, just about to dip the toe, breathless reporters,.. )the LS is all about sex. That's what is talked about, envied, disparaged, ...
From the inside looking out, the LS is all about your primary relationship with your spouse or S/O, and how that journey unfolds.
For a few in the LS, it really is "all about sex".
For many others, it is about building relationships with like-minded couples. The friendship piece really does matter. Trust, intimacy, honesty in a space where no one is embarrassed to be having fun\. Compare that to the issues of ordinary life.
