SEX

for men only...

You may want to take that laptop off your lap. Portable computers can heat up to 158 degrees inside. After an hour, that can raise the temperature of your testes by 3.6 degrees, nearly twice what it takes to harm fertility.

For better sex, crank the thermostat way, way up. Working on the same concept as Bikram, or hot, yoga, this momentary splurge on your heating bill will have you breaking the social taboo of getting sweaty together. Taboo-breaking ups her vulnerability and makes her feel closer to you. Plus, everything will just be a whole lot slipperier.

To get your partner in the mood, turn down the Barry White and feed her Good & Plenty. In a study by noted Chicago smell researcher Dr. Alan Hirsch, women exposed to the scent of licorice experienced a 13 percent increase in vaginal blood flow. That compares to a 14 percent reduction from the scent of barbecue smoke.

In a related study by Hirsch on penile blood flow, topping the men's list was an interesting pairing of lavender extract and...pumpkin pie. The number two slot? Licorice and doughnuts.

If you think yoga is a great way to meet hot women, think again -- it's a great way to meet hot, turned-on women. Certain poses, such as the eagle, direct blood flow to a woman's pelvis, increasing sensation, says Rutgers sex researcher Beverly Whipple.
