DAVID ARCHYMen's 3 Pack Underwear Micro Modal Separate Pouches Boxer Briefs with Fly

How do you wear these? I see only 1 pouch. I just got these, and didnt think I'd need instruction, but I do not see 2 pouches.

Very confused on the sizing... Some say run large others too small. Yet I can't order a Small for a 33" waist???

Do these enhance your buldge?

Is this price for 1 pair or 4 pairs as pictured?
