The biggest natural libido increaser for women is "AFFECTION". Women love to make love..this does not always mean sexual intercourse. If she feels affection, warmth, acceptance, & understanding from the man, she will respond accordingly.
This disease causes us debilitating fatigue..not just being tired, but feeling as if we are (as a friend put it) under a lead blanket and just cannot move. It is important that you understand her fatigue - it is unlike anything that a healthy person experiences. Imagine you've just run a 26 mile marathon in 102 degrees of desert heat with no water and no rest stops, and imagine that you've done this while at the same time having the worst flu you've ever had in your life! Imagine feeling that way 24 hours/day...7 days/week. How anxious would you be to engage in any activity that does not bring you a sense of love, understanding, and affection??? And remember, the fatigue is only ONE of many symptoms that she is suffering from!
Now, imagine that you do get the sense of love, understanding and affection that you need, so you are willing to engage in sexual activity. Wouldn't doing so be even a greater gift that you are giving, considering what you are hindered with??
Give her the gifts that she needs and I can guarantee that she will give the gift of herself.
Peace and Blessings
