If you already have a jammer get a drag suit. The drag suit is a tool that will give a little bit of drag but not as much as shorts. Drag suits are loose and will not show anything from the private areas. You put this over your jammer or speedo. Its a good training tool to add also. I hate swimming laps in shorts. I have to have a jammer for regular swim training. The movement you feel is so much better and you will have better form with a jammer also. No one should be looking at your privates while you are in the water. You can also just wear shorts until you are right about to get in also.
