How often should you wash jeans?

After about 2 uses.

3 times in a year

I'd probably wash a pair of jeans after wearing them 5 times .. more often in Summer
.. unless I'd done something to make them dirty (like kneel down in mud) then I'd wash them anyway.
I wouldn't wear the same pair two days in a row either.

Jean were designed for dirt work pants and it was a labor ,mechanic ,cow boy ,farmer dressing for it's last long fabric (cotton).Since girl they get hot on the male in those pants during work ,it become fashion wear for any young boy or male and as a dress formula even in offices or with coat and tie .Which literately women get ride of the Skirts that were blow by wind and show every details of secret to the males and start wearing the jean as men do ,later on it get so famous that each person cross the world start to wear the jean.This confuce the male and female both (same kind dressing) and phenomenon of the Gay & Lesbian appear all cross the world (girls acting like a boy and boy acting like girls)right now you can not say exactly it's a boy or it's a girl .From behind look like a girl ,tall hair ,a packed *** in the jean,color sport shoe,nail polished ,and lot of rings and earnings on face and the girl attitude of walk .From front he has mustache and beard and under the eyebrows are clean with a light makeup (wow that a guy) .Other side of the street ,an army cut hair with a big *** packed n the jean ,chain hang by side of the jean and cowboys show with a tie *** shirt on ,but from front a beautiful face with pear of big *** boobs that nipples are pop up and a cigarette in the hand and talking like boys that want to fight kissing another girl in the walk side.(Wow those are girls).Then this question it coming in your mind if that is a boy and those are girls then who the heck or what the hell I'm?
So long story short ,now you tell me how often I should wash my jean ?

After 2 to 3 uses.

There is an abundance of perspiration, and other odors that cannot be mask with sprays and colognes. Many of those odors do not light up until the pants/jeans become moist again with sweat. 4 to 8 hours of wear time and 'plunk' they go into the machine. Using a cold wash with white vinegar can save the day and most peoples noses.
Dry cleaning does not help much either for that same reason. They light up when moist and it is terrible to be next to someone who just does not get it.

I can only wear my jeans once and then I need to wash 'em. Being in High School and throwing a rod all day long keeps my crotch all wet and sweaty. Most of the time I'm going commando, trying to keep those jizzed-up eggs all cool. And, my dick leaks precum after every gym class, especially when we're wrestling, so those jeans get all crusty inside. I can hardly wait to get home and strip them off and let my balls breathe. Men have body odor too and my changing hormones don't help much. So, I gotta wash 'em after I wear them.

And if I don't do my laundry and they pile up, my older brother rags on me about how the laundry basket reeks like a dirty bookstore glory hole.
