How would you know though, in the 'honeymoon' phase?

Normal girls don't fuck your brains out without hours of meeting them. The reason men like crazy girls so much is that "they'll do things normal girls won't do". My crazy ex did a lot of sex shit that she'd try to get you addicted to, so you could replace her with a "boring vanilla" girl.

But I don't think they were having sex with 60-year-olds.

The vast majority of these "illicit" relationships involve girls age 13-17 dating guys in their 20s or sometimes 30s. The better looking a guy is, the older the girls will go, and the crazier the girls are, the older they will go. Chris Hemsworth is 39, they'd be lining up for him.
