fluid bonding,its the act to have unprotected sex.
one hour after a simple kiss, dna of the partner can be sampled
french kiss unify bacterial pool of both partner and stay for several day
polyamorous people are very strict on std and safe practice.

it is not a bad idea to impose a safe sex practice
always use condom, no french kiss, no oral
but we are into oral and deep kiss
so it is impossible to avoid
rules are meant to be broken, there is not rule without consequence when you broke it.
How you deal rule non respect is reverse proportional to the level of honesty.
"if you cheat i'll leave you" then she'll lie.
so it is better to handle now the fact that she will french kiss, blow and be filled by another guy.
And you know that it could happen to you, you really enjoy fluid bonding.
How much time she taste peanut butter before you can kiss.
She puke sometime, all discusting thing that are not permanent
she smoke joint anyway with people.
That bareer is virtual.
and like any other dude who had her before you. it dont matter with time.
Still we need to be carefull with std.

I is still important for the respect to each other to limit fluid bonding as much as possible.
And maybe end an activity if needed.
While still possible that this rule can be broken. its important to not punish because you want to know as soon as possible.
STD are real

Its very important to be selective.
And make it for love, not just fun.
