Fruit Of The Loommens Eversoft Cotton Shorts With Pockets (S - 4xl) Casual Shorts

Do these have a fly?

Can I wear these in public or will a bulge show?

Is there an unraveling problem?

I ordered 3 2-packs of each color. Black,blue both had 2 shorts in each package. The grey package only contained 1. Anyone else have this issue?
