How is exposing yourself to other people different?
By the nature of the thing, streakers were tacitly admitting that they were doing something wrong. They “streaked” at a distance, generally in front of a crowd, and nobody really got a close-up stare at their genitals. Further, although they were fewer than men, female streakers were not completely unknown.
It seems self-evident to me that streaking as a phenomenon was quite different from exposing one’s self at a party, by definition an enclosed space, smaller than generally chosen for streaking, then shoving your member in the face of a girl who had, presumably, invited it in no way.
Streaking was a well-known phenomenon. I never saw anyone behave as described at a party. This is why I asked if anyone else had observed such behavior.
