I think it's 'cause guys build up to an emotional explosion, rather that just get it out in the beginning. Men are forced to be so much more reserved and sensitive(totally against their nature on a continuous basis) these days around women now days, they can't unleash their emotions until it's boiling out of them. If you're going to date someone, date someone who practices martial arts or blacksmiths on a regular basis, then at least you know you've got a guy who's been able to release some tension.
