Fluid bond

In some monogamous and non-monogamous relationships, partners may feel comfortable and safe enough with each other that they decide to have unprotected sex. This agreement can be called a fluid bond because these partners now exchange body fluids.

Partners in a fluid bond may choose to continue having protected sex with other partners outside of the fluid bond.

Some things to consider when adding new people to a fluid bond:

  • Talk about who is currently in the fluid bond.
  • Talk about how and when people are added to the fluid bond.
  • Get tested for STIs.
  • Talk about STIs, testing and window periods.
  • Talk about what to do if there is a breach in the fluid bond, or if someone in the fluid bond gets an STI. 
  • If it’s relevant, discuss how to prevent an unplanned pregnancy or how to plan a pregnancy.
