I was raised in Bedford Stuyvesant Brooklyn and normally straight guys did not hang out naked together.
However, when I joined the boy scouts with other boys in my community we did go camping, and it was there that I found that straight guys seemed to like to swim naked in ponds and lakes.
I was actually more embarrassed than the straight guys. They were all absolutely comfortable hanging out naked because there was no sexual tension between them. For them it seemed quite liberating. The group was also a mix of Latinos, Blacks, and whites.
I happen to know many straight guys in the military who have similar stories of skinny dipping. Usually it occurs when there is a secluded area to swim. My own brothers have also done it, and none of them are gay.
just because it's the norm in the gay community for two guys to chill out naked DOESN'T mean that it's the norm in the straight community. you say plenty of straight guys hang out naked let alone or trying to see another man naked. maybe where you're from BUT where i'm from, most straight dudes aren't doing that. it's just not the norm or something that is socially acceptable. maybe the folks that like to joke around about being gay, are comfortable about themselves and don't care about what other people think and all BUT that's about it.
just saying, most straight people view something as two guys running around naked skinny dipping or being in a hot tub as being homoerotic or gay so to take something from a video that pertains to a fantasy of a gay man and saying that it's an important message wouldn't fly. if you said this to most straight people, they would tell you that you're putting them in an uncomfortable position. some of like a straight female forcing herself onto a gay guy.
