There is No “I” in Threesome (HBO Max documentary film) — Plenty of people want to try a threesome, but (arguably) the vast majority of these endeavors tend to backfire. That rule is not set in stone, but given that the tagline of this film discusses how someone always gets “screwed,” let’s just say, “Buyer beware.” Non-monogamy is always a lot more complicated in reality than it would appear to be in fantasy, so settle back and watch these couples light their relationship on fire for your entertainment. You’re welcome.
