Browsing: advice for swigers

I’ve been swinging on and off for years as a single guy. Just over a year ago I met a woman who’s kinky and pretty open minded and into trying BDSM. I hoped that I could draw her into swinging but she’s very reticent about getting started despite her wanting us both to try some bi fun. My best efforts in making her feel secure in our relationship don’t seem to be working as she still struggles with taking that first step. I’m finding it frustrating because I’m missing the lifestyle but don’t want to ruin what we have now.
