There isn’t a reliable public count for how many bisexual swinger couples are out there, but forum activity suggests they’re a visible subset of the swinger scene rather than a tiny anomaly.

What the public data shows

  • Swing lifestyle forums have dedicated bi-couple sections with thousands of posts and hundreds of threads, which points to steady interest and participation.
  • Recent forum discussions also show people asking how common mutually bisexual couples are, and replies say it varies a lot by region and venue.
  • Some communities explicitly list bi-couples as a separate discussion group, which suggests the category is recognized and active online.

What that means in practice

  • “How many” is hard to pin down because most swingers do not publish orientation or relationship style in a way that can be counted cleanly.
  • The best-supported answer is that bi swinger couples are common enough to have their own spaces, but not common enough that every local scene will have many visible couples.
  • Location matters a lot; some places report lots of options, while others say bisexual couples are harder to find in person.

Simple takeaway

If you mean online and in swinging communities, they’re definitely out there in noticeable numbers. If you mean an exact population estimate, public sources do not give a trustworthy total.

TL;DR: no solid census exists, but forum and community evidence shows bisexual swinger couples are a real, established part of the scene.
