For me, being fluid bonded is a huge step of trust. I am fluid bonded in the long-term V relationship I am in and am discussing the option of being fluid bonded in a new V I am entering.
I've had many sexual partners and used condoms with all bar about 5 men. For me, being fluid bonded is the ultimate sign of intimacy and desire on my behalf to be in a long-term relationship with the person I'm bonded with.
I always have a full health check before entering a fluid bonded arrangement and ask that my parnter/s do exactly the same.
