Person A chats with five people. Two seem okay, two seem like poor choices, one seems unhinged and is quickly blocked. Of the two good options they go on a date with each, selects one of them, and forms a relationship.

Person B is deluged with messages, many of them vulgar. After some filtering, they end up trying to hold coversations with twenty different people, but struggle to form a connection with any of them. Eventually they go on a date with the person who seems the best, it goes okay, and they form a relationship.

In this example, is person A or B able to be "choosier"? Which experience would you prefer if you could choose? I would argue that quantity is not valuable independent of quality. Or to put it another way, I suspect you would find that most single women would argue they have no greater number of acceptable choices than single men do.

The (obviously real) difference in the number of men sending women unsolicited pictures of their genitals compared to women sending men such pictures isn't really relevant.
