The term is outdated, IMHO, anyway, and has been misappropriated by TERFs these days. Outdated because it assumes strict binary genders on both sides. I don’t usually date men, but that doesn’t mean there isn’t sometimes some attraction, but consider myself agender, so neither lesbian, gay, nor straight can possibly apply to me without a starting gender, and I don’t discriminate against trans people and the terms totally exclude other non-binary people who could be my partners. So, polysexual is a good term that I’ve found useful at times, but generally I just don’t bother using any of that terminology. Every decision about my attraction and desire to date someone is specific to that person, not defined by their gender necessarily. So, I use pansexual if forced because it doesn’t limit anything up front. But, I don’t usually have much desire to advertise my sexuality anymore because the terminology is just so imprecise anyway.
Unethical and hierarchical non-monogamy is risky emotionally, ethical non-hierarchical non-monogamy without envy driven rules is not any more or less risky emotionally and can be very rewarding with truly loving partners as you don’t have to rely on a single person to provide things you need when it’s painful for them to be forced into providing those things since you can’t find another partner to provide those things.
Especially bad for ace or disabled people or women with vaginal issues and men with erectile issue when their partner is left sexless, but they need it to be fulfilled for example, or when one partner needs lots of physical touch but the other has trauma related to it, or a partner who loves to worship breasts, but has a partner with very sensitive nipples, but other than these issues the relationships are great. With ENM those things can be fulfilled by other partners while maintaining an even stronger relationship with the first partner.
