What brand underwear do you wear?

I’ve been wearing Bonds briefs (I’m from Australia) for years but they always shrink. I get large, I’m 80kg, lean and workout 5 times a week. My package on the flop is average so it isn’t an anaconda yet but the issue is they’re so tight. Some don’t shrink as much and I prefer my older pairs. I wash in a cold wash too.

Any suggestions on brand and maybe fabric? Could avoid shrinkage.

I lay here in bed, changed my undies to a fresh one even those I just showered 2 hours ago because they’re too tight.

When I get morning glory, it’s very uncomfortable. Send help
