Helpful advice for you undersexed people, from Slate:

Having a TV in your bedroom means you get only half as much sex. A study of 523 Italian couples found that those with a TV had sex four times a month; those without a TV had sex eight times a month. Among people older than 50, TV reduced the average frequency of sex from seven times a month to 1.5. The study did not make clear whether 1) putting a TV in your bedroom makes you have less sex or 2) having less sex makes you put a TV in your bedroom.
