THE GREAT SEX EQUATION
Need another reason to never buy another pack of cigarettes? Lighting up restricts blood circulation, which may make it harder for your body to become aroused.
Aim for a healthy weight
Shedding excess pounds can make you feel sexier, suggests a study out of Brown University in Providence, Rhode Island.
Watch the alcohol
A glass or two? Fine. But be careful: It can take a woman about twice as long to climax when she's had too much to drink as it does when she's sober.
Forgo the french fries
Downing high fat food leads to clogged arteries, which makes it harder for blood to circulate to all parts of your body, including down there.
Put yourself to bed
And get some shut-eye. Sex-hormone levels -- and thus your libido -- may take a nosedive if you're walking around sleep-deprived.
Hop off the couch
No, really -- get moving. Regular exercise can boost your libido by increasing the levels of endorphins and sex hormones in your body.
Asparagus and avocados contain niacin, which may trigger increased sexual sensation; broccoli's got vitamin B5, which aids sex hormone production.
