Are they supposed to be so tight!?

Recently bought some RST pro series 1 piece leathers, and they're extremely tight in some areas. Legs and front torso are fine, quite tight around the arms but nothing too bad. but around the shoulders and groin are extremely tight, I have to walk around like a monkey so my bits aren't being pushed up back inside me! I called the shop where I ordered them from and they said that all of the different (chest) sizes still had the same lengths. They're fine when I'm on the bike, but impossible to take off or walk around in....

Will they loosen up a lot?
Or could I alter them in the groin area?

The shop offered me to replace them with a less racier set, but I would like to keep the same style....anyone know a good set for me? I'm about 5'11/6

They'll loosen up!
