Fluid bond

A fluid bond is when partners make an intentional decision to have unprotected sex.

In a fluid bond, partners may exchange bodily fluids such as semen, ejaculate, secretions, blood or saliva.  The risk for sexually transmitted infections (STIs) and pregnancy is higher in a fluid bond, because barrier protection (such as condoms and dental dams) is not used during oral, anal, or vagina/internal genital sex. Some people choose to have STI testing done before entering a fluid bond.

It’s a good idea to talk about what a fluid bond means to you and your partners so you’re on the same page.  Some things you might want to talk about are:

  • Who is currently in the fluid bond (ie other sexual partners).
  • How and when people are added to the fluid bond.
  • Getting tested for STIs including window periods.
  • If it’s relevant, discuss how to prevent an unplanned pregnancy or how to plan a pregnancy.
