I believe the K2 has an effect in the calcification, that could prevent the blood flow to the genitals.
Perhaps not so much to do with iodine, but more magnesium, boron; I would up this to 18-30 mg.
Then diet.
"Why is this Super Vitamin K2 missing from our diets? Because we have gone from Nature’s grass-fed ideal scene to a rapid grain-fed and grain-finished meat and egg diet. Unfortunately, animals that are kept in feedlots and cages do not produce Super Vitamin K2. It only comes from a 100% grass-fed diet out in pastures. This is why it is so important to eat only grass-fed and pastured animals and eggs." http://turbochargedturmeric.com/products/super-vitamin-k2/vitamin-k2-for-opti...
