Why do guys do this?

I didn\'t realize until just lately the problems excess masturbation causes.

Listening to other women talk on more sexually related sites ... so many guys can\'t get/keep it up or don\'t cum because they\'ve masturbated one or more times on the DAY they had a date - I mean a date that would include sex - not a first date, etc. A meeting with a woman where it was understood there would be sex.

I know a guy who worked at an impotence clinic and he said one of the first treatment recommendations they made was that the guy stop masturbating.

I don\'t get why a guy would whack off when he knows he\'s getting laid later on in the day - or why he wouldn\'t want to save up some energy and actually lay off for a few days, in anticipation of a date.
