People don't agree with what I'm going to say, but nonconsensual *nonmonogamous sexual relationships are physically and emotionally abusive. Physically because they potentially expose the non-consenting to disease, and death by disease. Emotionally and actually financially, because of gaslighting, withholding, gaslighting. And even with laws on the books, all abuse is underreported, and then when it is, there's the victim blaming mentality, from report to trial, if it makes it that far.
