What would a romance novel for a male audience look like?

I was reading a post about the lack “mean girl” female main characters in romance novels and one of the users quite insightfully pointed out that the audience for romance novels are women and women who read romance novels aren’t usually women who were or identified with “mean girls”.

So they’re not at all interested in reading about the women that bullied them high school finding love lol. They’re interested in the sweet, quirky, (sometimes virginal) girl who falls in love with the brooding, grumpy, sexy male romantic interest who sweeps them — meaning both the character and the reader — of their feet.

This leads me to ask, what would the male version of a romance novel look like? Yes I know there’s a small minority of men that read them but they’re guests. They’re not the targeted demographic.
