Irritatingly itchy.

Out of nowhere, my privates started itching yesterday. It wasn't too bad so I didn't think anything of it. I went swimming and sat in my wet bathing suit for quite a few hours and I think that made it worse. I just went to the bathroom and I got a mirror and looked down there, got a flashlight and spread the lips open a little bit (sorry to) and it looks like it's been rubbed raw, kind of like what a sunburn looks like when it's peeling. It's terribly uncomfortable. Anyone know of anything I can do to ease it and/or make it go away or do I need to tell my doctor next time I see her?
