Leg bindings makes big difference

[Torchwatch]

The wider the groin in a suit the less likely you are to drop out by accident, those with larger balls will need a wider suit at this point. What fits one person may be less comfortable for someone less well endowed.
Although exercise builds muscle and overeating builds fat we don't have control over the size of those parts of our bodies determined genetically. Find swimwear that suits you are wear it confidently whatever your body type.
