Why should'nt guy wear panties?

Simply because it shows that the guy is uncomfortable with his sexuality and should consult a good therapist.

Panties are far more comfortable than men's briefs or boxers.  An obsolete social stigma is irrelevant, in fact, it never has been relevant.

i tried to wear a pantie once, but i started having severe pain n my balls, so i took it off

Like anything else, you need to get the right fit.  Perhaps you needed a larger pair, or a wider gusset.

You might think mens underwear is more comfortable because it is supposedly designed for men. This is usually claimed by men who have only worn mens underwear or who have maybe tried inappropriate womens underwear.

The truth of the matter is. Mens underwear has not changed much for centuries. In my experience mens underwear is not very well designed and (pardon my specificity) when I am wearing mens underwear I find myself constantly having to "adjust" my penis and scrotum to be comfortable.

I've found some mens underwear that fits much better (Cherskin is the best) but years ago a female friend suggested I try a certain brand and style of panties (OnGossamer Boy Short) and they were the most comfortable thing I have ever worn. Since then I have experimented with other panties and found that they are much more comfortable than mens underwear and they come in so many styles and fabrics that I actually had a fun time shopping for my underwear!
Just be sure that the underwear has enough fabric in the front to contain what you need contained and beyond that... Go crazy. It is a whole new world.

because thats just not the way it goes bud - keep trying to find draws that make you feel good ( comfy-airy -whatever) silk- boxers-grape smugglers. there are so many different kinds of underware out there. if you are hung up on  getting into womans pantys ( not while a woman is in them or for a sexual reason ) I have to say that I think you have issues. I don't want to seem like an ass but there is a reason for marketing mens and womans underware - one is for men and one is for woman . Whats next - pantyhose and a purse? common brain function should be used here - keep trying - your boys will thank you for your efforts . whats wrong with freeballin?

Women wear pants so why shouldn't men wear panties. Women have stolen men brands, Jockey, Fruit of the loom and Haynes so why not return the favor by wearing their panties. Women think that men that wear panties are soft and not macho ! If that's the case, stop wearing pants ! Seriously, all joking aside, women have all the nice clothes and underwear After much research, Women have at lest 6,000 to 7,000  selections of panties ranging from brands styles and colors while men can pick from Jockey shorts and boxer shorts. My, what a simple decision for men.  I like so called Granny Panties, full brief panties feel comfortable and support my additional parts. Olga panties are the best because they stretch both side to side and up and down and give my dearer some hope of shape. Thongs are out. If women complain about panty bunch their their butts, then thongs are out also! Don't you agree. Men wearing panies are great !  Any comments !
