Does your LD spouse always seem REALLY tired at a normal bedtime. It seems my wife has to have a minimum of 8 hours sleep to function properly, while I can get by on 5-6. So when we go to bed, at reasonable times, I am still EASILY ready for sex, while she acts dead tired. And we both put in long hard days, so it's not like she is overworked in comparison to me. Definitely does not help the sex life.
