Possibly: If your bicycle saddle is a poor fit, pressure on your groin's arteries and nerves can cause this problem. Most cases are temporary, and can be fixed by a better bicycle seat which doesn't press so much on the tissues in question. It's a good idea to go see your doctor and have an examination for other possible causes such as clogged arteries or early diabetes. Please see your doctor soon.
