From what I've gathered by listening to women, there are fundamentally different problems. "Attention" is not valuable in itself. Getting spammed with dick pics is about as appealing as any other kind of spam. No one looks in their spam folder and thinks "Gosh, all of these advertisers think I have money to burn! What a great compliment!". It doesn't show any personal interest. It's not a sign that the other person is going to treat you like a human being instead of a sentient (flesh-)wallet.

The difference in experiences starts early in life. For boys, girls showing interest in them is often an exciting and empowering experience. For girls, often as not, the first sign of sexual interest is a creepy older man making uncomfortable comments at them when they're 11 years old. IIRC this shows up in mental health statistics -- boys who start puberty earlier tend to do better; girls who start puberty earlier tend to do worse. And of course there are different social standards applied to men's and women's sexuality.

Women also have much bigger safety concerns than men do, and have a harder time getting anything done about attacks afterwards.

I think all of this does make it harder for women to understand the destructive loneliness that a lot of men (particularly young men) face. I've been there, and I remember that trying to talk about with my female friends was a frustrating experience. But over time I've come to see that women don't really have it any better than we do. We're wandering through a desert looking for an oasis; they're swimming through a lake of garbage looking for an intact water bottle.
