Men's existential dread is that they'll never have sex. When this goes well, it motivates them to gather resources, be likeable respected and charming, and make a move on girls.

When it goes badly men engage in reckless dangerous behavior, or rape.

Women's existential dread is that they'll be abandoned. When this goes well they reinforce prosocial communities, dress up to look good, and encourage positive emotional bonds.

When this goes bad, they neuter you (cut off your balls) so you can't leave.

The mother is getting her daughter to cut off her sex organs so she'll remain forever a child and never leave.
