For me, this brought back bittersweet memories of the gay nudist pool parties I used to attend when I lived in Los Angeles.
There was sort of an unspoken understanding amongst all of us bros that any intimacy we shared (along with it needing to be consensual) would most likely only be temporary. Unless we got the chance to "hook up" again with the same guy at subsequent parties.
There were some male couples who'd attend while married or dating. In those scenarios, it was up to them to communicate their boundaries with their fellow gay dudes. Consent was highly valued among this group.
The act of kissing, holding, and climaxing with a temporary companion somehow felt both empowering and melancholy at the same time. But it also provided us single guys with a common nexus of gay brotherhood.
