Men's briefs don't hold the jewels in place

I bought several of these briefs thinking they'd be good for the environment. They may be good for the environment but if you have testicles they make for terrible underwear! Trust me, you don't want to trust your 'boys' to these briefs because they won't feel at all secure and you spend all day adjusting yourself, which isn't exactly polite behaviour in company. Not sure what the problem is but I suspect the design and/or the fabric. Either way, I stick with boxers from here on out.
