Multiple friends with benefits relationships is just informal polyamory without the honesty. Polyamory is literally more ethical than y’all who do “platonic fucking”. At least polyamory involves consent and knowing who each other is also sleeping with. Like y’all are not better than polyamory people. It’s way riskier and kind of crazy to be doing casual sex, even with friends, because you don’t know who else they’re sleeping with or how many. You don’t know if they’re using protection with their other sleepover buddies and if their sleepover buds are clean. A lot of young people jump into bed without discussing any of that. And even if y’all do talk about it, people lie all the time. Like ethnical non-monogamy is better than that. You are the unethical polyamory. You’re open about being not monogamous, which is great. It’s the unknown amount of partners, inconsistencies with practicing safe sex with multiple partners that is the issue. You do not know for sure. Y’all not better than openly polyamory people, because unconventionally looking people get around too with other unconventional looking people all the time. STDs get passed around all the time and some of them ain’t curable. Even monogamous couples aren’t safe from lies and STDs. You think a more casual relationship is going to be safer and have more trust?
