Is it unhealthy or justified for men to be terrified of women?

And could the following be considered childish, or justified?

Scenario 1: A young man (with severe self doubt) finds himself face to face with a woman (who smiles at him) at a party or bar. He sweats profusely, trembles, and runs away screaming in fear.

Scenario 2: A young man is walking alone on a rail trail. Momentarily alone, he sees a young woman walking in his direction. Considering they are on a former railroad track, he panics and screams "TRAIN!". He means the woman herself is an oncoming train, her legs are the pistons, her feet are the wheels, and her voice would be the train whistle. He runs in the opposite direction trying to avoid getting hit/run over by this "train" (aka rejected or humiliated for being not attractive enough).
