I chose B. DH wants it every day so I never "miss" it long enough to initiate it. (We definitely don't have sex every day, but he would prefer it. More like 1-2 times a week.)
I voted SS. We both occasionally try to initiate, but we have very different sex schedules (schexules?) So we very often shut each other down. He likes night, I like morning/earlier evening. And we''re both stubborn and can abstain for stupid lengths off time. So I guess somewhere between C or D.
