Ok I'm not sure this will help (and I've posted this multiple times on TE already) but it might solve some of the general irritation. I had a revolving door of yeast infections - like 6 a year - and tests never showed any reason. After a doc suggested I move to free and clear (and biodegradable) laundry detergent my yeast infections have become something that happens only if I take antibiotics. The new detergent halted it in its tracks. YEAH!

So, if you're trying to cut down on irritation (which is maybe partially caused by a chamois, which you wash in detergent) eliminating the dies/perfumes/mcnasties might just help. Ya never know, but it definitely has changed my life.
