Background checks and other parts of vetting

I've done background checks as part of the vetting process along with sexual health testing (STI/STD), but do you continue to do them? Whether your non-monogamous or monogamous. And how often do you do them? Do you stop after awhile?

The second part of my post: How often do you go through your likes and limits with your partners? Do you just do it once and never again? Do you do it once officially like mark it down these are the limits of myself and my partner, then verbally if things change as you grow, you just take a mental note of the change? Or do you go through this periodically?

Vetting can't be empirically tested, so its only good until it isn't. I am active in my local scene for about 16 ish years, and the number of people who were ok till they weren't is shockingly high, common garden folks, educators, community leaders of all genders, but these people who became not ok, were mostly men. Once you get involved with someone you are their next vetting reference, and likewise and that is not something you can continue doing. Once you are involved you have, with best information available made your choice, and its only if you become a victim, or find out about a past issue, you don't know about that removes, calls into question that original vetting. Been there and ended an involvement on the spot, when new info came to light.

STI tests are empirical, but again only good until they aren't, that space between tests, requires someone ethical, and careful, consistently so, and even those who are careful can be caught out, or do something out of the ordinary. With sexual activity condoms and other forms of birth and STI control are vital and must be applied, used consistently. That one time you don't, is the time there is likely to be an issue. STI tests should be ongoing if all parties involved are sexually active, regularly, and not fluid bonded, and you can have folks, even in a poly setting who are sexually monogamous, but poly regarding other non sexual activity.

Likes, limits, boundaries are fluid, in some cases, so will fluctuate, from time to time, so regular discussion, and or openness to those discussions is vital. So yes at the start as part of negotiations, building the dynamic, involvement, the foundation, but it does need built in that this can be discussed at any stage, both casually and formally. Its certainly up to those involved, from top down, and down up, that an atmosphere of discussion always exists.
