Male, not insecure much to my knowledge; I think the split here is "I wouldn't just fuck you". As far as I understand the world attraction for women to men is much less based on "beauty standards" and more other factors.

Everytime I said to the women in my life "That guy's hot, isn't he?" on the basis of what I think would be an attractive man I get back "God, no". Think like, I don't know, Ryan Gosling or Alan Ritcherson or and then Jack Black comes up and their heart beats ouf of their chest, their eyes get comically large and they go "AWOOOOOOOOOOOOGA". I've since learned I have no idea what hetero women find hot and that people like Ryan Gosling or Alan Ritcherson are, going by looks, more like a male fantasy of how and what to look like.

So coming from the womens POV that sounds like a compliment, but to the guy it sounds like "I don't think you're physically that hot.", because he's Jack Black and not Ryan Gosling if that makes sense. I think the ire here is in large part that women are often complimented on their looks, rarely on their skills and it's vice versa for men, which is why he probably wants to hear he's Ryan Gosling and not Jack Black.

All very much generalized and such, but that's what I figured. Given her version of the story I think storming out is a bit much, though.
