Merry christmas to you too T O M :) Yes years ago when I plagued with candida/ trush/ fungus infections, I tried coconut oil down south. Found it kind of abrasive and did nothing good, felt uncomfortable to the membranes down there. I found ozonated olive oil to work a little, but the smell of ozone is a turn off. Later I found better ways to do it, like i.e aloe vera gel mixed with Iodine and a little essential oil. Felt much more natural" than oils. Essential oils are ok because they are light and actually have a near correct PH for the area; approx 4.
More accurate symptoms and I may help further; PM if not very Iodine related:)
