A saddle is very specific and personal.
You haven't disclosed any personal information, so how do you expect us to help you?
You could weigh 100lbs or 250 lbs ... your "private area" or "balls", as I like to more simply call them, may be tiny or huge, as may be the rest of your behind.
As meanwhile has stated, they do make special saddles for about everything, so maybe it would be best for you to contact your LBS about this.
You may also be helped by changing the position of the saddle by heightening it or tilting it a bit more forward, to have more pressure on your behind and less on your balls.
