And the LD people may feel the same way about HD people, as far as just not getting it.
In your case, is your spouse on medications that could lower it? Are there any medical or emotional issues going on? is your spouse no longer in love with you? Do you know why they may be LD?
And if you are saying you will make other arrangments then that might be what you have to do.
If a person is LD for whatever reason, and if you were to tell them you are going to make other arrangements if you don't get sex,that will likely not get them to switch and become HD or even give in for that matter, it really depends on the situation.
