OK I love to go to the beach and swimming and to theme parks but once I get my legs the least moist I get a rash in my inner thigh. Is there anything I can use that is water proof or water resistant. I notice a lot of girls have this same problem but that's when they wear skirts or at least what I found. I am not fat I just have bigger thighs that rub and it is painful and I need help because I am always wearing shorts. Thanks so much

There are a lot of good sunscreens out there that are water resistant. You will still need to apply often. Have you tried any of them yet as a short term remedy?

When I was pregnant, I used baby powder for the non swimming days. When I went swimming I used baby oil. The only thing with the oil is, when you are out side, you have to make sure to put a layer of sun screen over it. The sun screen also helped reduce the shininess of the baby oil.
