My mother is a nurse and last month she got sick and stayed at home for more than a month and this made my Dad stay all this time without sex. He's insatiable, some days after being with me he waits for my Mom to come from work to do her too, but last month he was knocking his head against he walls: no mother, because she was sick and no me because Mom was at home all the time. When she got back to work everything when back to normal.
