Something similar happened to me too, except the lesions. I got 2 yeast infections in one month and my skin looks dried out and peeling, even though there is moisture from the discharge. I haven't been able to cure myself yet, so I can't really help. You should go back to your doctor to make sure that the lesions you are talking about aren't something else, like a herpes infection.
See a doctor. The cocoa butter might be bothering your skin by drawing out too much moisture from it. Home remedies are not a good idea here.
