I don't know anything about Borax helping one's libido. I do not thing Miracle-Mineral-Supplement would help with that eighter (have taken it for a while and did nothing to my libido :) )
However, try practicing yoga. All the slow movement, focus, certain breathing frequency, meditation releases hormones that , as a result, make you feel like you long to feel...if you know what I mean. There's also a natural supplement called "libido: - in a green bottle that might help you.
Another thing,you may be suffering from clinical Depression and you need to consult a doctor . Medication may help you tremendously...Female pleasure is born in the brain (almost the whole brain is active during a female cllmax), so treating the brain is quite important in this regard.
