DAVID ARCHYMen's Underwear Bamboo Rayon Breathable Ultra Soft Comfort Lightweight Pouch Briefs No Fly in 4 Pack

I see someone said they’re a 38 waist and wear a medium comfortably but chart says medium for 32. I’m 32”. What size should I get?

Do these have a lot of stretch? Or keep the boys in place all day?

are these tagless?

Is large not available???
