I was a robot club nerd so the concept of locker room talk is foreign to me. But now as a grown up, I can't say that I've ever felt unable to connect with another man because I can't make a sexually aggressive comment about a coworker or mutual acquaintance.
Note that the "sexually aggressive comment" can just refer to a plain "sexual comment" (which changes the whole sentence's meaning).
And it's labelled "aggressive" because of several centuries of hardcore religious puritanism leaving their mark on all aspects of US culture. Sex is naughty. Sex talk is aggressive.
Only we didn't speak specifically about such talk here.
The parent said "There's some value in being able to talk bluntly with other men. And I'm not sure it's much worse than what I observed groups of women talking about".
And this was immediately taken to mean "aggressive sexual comment".
