I think you’re spot on about the autonomy angle. Even if it’s a video that I would enjoy watching at that moment, I always feel uncomfy knowing that I can’t really say no at that point.

Anecdotally, I have noticed that it is more prevalent of a thing for men to do, but there’s definitely a lot more going on than this being straightforwardly gendered. A friend speculated that women are less likely to do it because they are more likely to implicitly understand and be able to navigate situations involving coerced consent. Others in the friend group disagreed with the assertion that this is primarily a male phenomenon, citing their own personal experiences with women showing videos in this manner too. I don’t know what to make of it overall, but certainly I’ve heard enough dissenting opinions to be sure that my own anecdata is not representative of everyone’s experiences
