Women wear bib shorts backwards. That way the single strap that we wear in the back goes in the middle up the front. This is why they are so picky about things. You don't want that single-piece too narrow. For this reason, I am designing boob shorts....


But seriously man, they're boobs not nuclear warheads. I'm sure its a matter of preference but I can't imagine the straps putting more pressure on the boobs that a tight shirt - and men have nipples too so that can't be the reason.
