I heard this more than once from people online and the responses were hard water from wells, high sulfur content, hard water etc. Try a water softner and whole house filter which may benefit you greatly. More than likey what the is happening is the chemicals in the soap that you are using are stripping the body oils from your skin and that is highly irritating. Try moisturizing with fragrance free aloe and shea butter lotions that do not have chemicals and synthetic preservatives in them ( very important). I find the softer my skin the better it feels. I hope you find the solution. Good luck.
