Here is a thought experiment for heterosexual men. Imagine you have an opportunity to have sex with a female celebrity you feel a strong erotic attraction to. You can keep who it is to yourself. Imagine that the good witch of the north suddenly appears and tells you that all you have to do is click your heels together and think of ... whatever it is you desire.
Is the first thought comes to your mind that this celebrity would watch you masturbate? Me neither. There is something juvenile about these men, they are like petulant little boys acting out because they can't get women to take them seriously as sexual beings.
And now, Al Franken, whose excuse is that he thought it was funny. Franken gives the game away. This is all about acting out instead of growing up.
What it isn't is "toxic masculinity".
Go back to that thought experiment I started with. It's narcissistic. Why do I say that? Because the woman's desires and hopes never enter into it.
What we have here is not an excess of masculinity but a masculinity deficit.
