1) It is incredibly easy to tell when a woman actually wants sex versus she is doing it for you. This is why it is so hard for LD woman to fix their situations, they basically can not give convincing performances. You can not ML to a woman that has no desire, you can only have (hooker) sex.
2) If sex is work for the LD spouse, then eventually they will resent having to do it, they can not keep it up. Also, as the HD spouse, you feel rotten for making them do it. Compare this to shopping. Let say you like to shop every weekend. You husband openly admits that he does not desire to shop, but will if it will keep you happy. So for the rest of your life, your ONLY choice for shopping is to drag him along. Either you will drop the shopping and resent him for the fact you had to drop shopping, or you will cheat and find another shopper. Basically, nothing good is going to come from this situation.
3) Profound expressions of love are to give your spouse what they want. Marriage is supposedly all about giving. He is not asking her to give sex, he is asking her to give desire, HUGE difference.
