Panic.

Both my opinion and scientific studies who that women would be the ones to panic more when under pressure than men. Women are naturally more emotional creatures. It has to do with horomone production and actually the shape of the brain as well. (Or so I learned in a psychology course) Men are naturally more logical beings when it comes to life, let alone pressure. When put into a stressful situation, men tend to rationalize more, where as women base their initial decision off of emtional responses, hence one's gut feeling.

The only time I know where men panic is when the woman they love turned out to be unacceptable and disapproving of the sincere love they wish to impart to the girl. Its not only women who panic you know. Everyone has their own needs and the lack of cooperation of one leads to the loss of the other and the loss of the other cant contribute to the welfare of the other.
