Bawls discomfort, should I go 4 any specific brand ?

Hello, Ive always used cheap whities from Walmart. But then I started puberty and I switched for Loose fit boxers, thought it was a good idea, whities were killing my bals, they got to tight. Unfortunately the loose ones were ok as long as I didn't moved too much, otherwise my testicls jst end up hitting my thighs or sweating to much. So I just switch to my old whities when exercising or walking a long distance, even if those are tight, tried both whities and tight boxers but it's just the same discomfort. I'm looking for something that provides a comfortable support, and preferably in Youth sizes.
