Arguably hook ups / one night stands drive STDs more and always have.

Anecdotally every poly person I know is (relatively speaking) quite diligent about STDs, getting tested way more than most, informing partners etc etc. Sometimes it seems to me like poly is actually a spreadsheet fetish with relationships on the side.

I think polyamory is more threatening to "traditional" values due to emotional risk / complexity and impact on family structure, parenting etc. One of the gnarlier problems is wealth transmission.

In many countries you are de facto with someone after just 2 or 3 years, this is already crazy, you get in a relationship with someone and a few years later you owe them half your house. Bring poly into the mix and if you a) have assets and b) cohabit then things can get messy real fast.

Very basic stuff like welfare and taxes haven't really caught up with this either yet, practical things like what do you put in the "partner's income" box on many government forms. The bureaucracy is really not set up for this.

Any data on the ONS? It seems swingers are higher risk than the general population. Although it doesn't compare the risk of ONS to them.

I'm not aware of any studies I find very cite-able or credible, sorry.

Complexity and risk are the real things to watch out for. If everyone involved isn't emotionally stable, it can be a nightmare for other partners and children.
