I would like to add to your post that in the case of many LD's, they are ALWAYS in a position that feels they would be bothered by sex. Now the burden falls on the HD partner to CHANGE their mindset at that moment to being receptive to sex. For example: My wife ALWAYS has a cluttered mind. She is ALWAYS not aroused or receptive. To get her to let go of the thoughts and stress of the day, I must relax her body and brain (hopefully). So the process to RELAX her and try to arouse her is ALSO the same process to relax her and put her to sleep. So this process results in arousal 20% of the time and results in falling asleep 80% of the time. Now the worst part, if the HD guy does not guess correctly which way the LD is going (sleep versus arousal), he is dogmeat. And the clues she gives off are NOT very easy to see. So she ends up losing respect for me because I guessed wrong, and thought she was aroused when in fact she was basically asleep.
