Plain water is not good for use as a lubricant for masturbation, as you found out, and it will cause friction irritation. Use baby oil, shampoo, or something that will not be harmful to your skin.
With redness and skin peeling, it sounds like the lack of lubricant caused friction irritation which should heal on its own as long as nothing irritates it further.
