You meet..... how to tell UPFRONT if the sex will be great! Is there any way to surmise whether sex will be mind-blowing before you even take your coat off? Yes, says psychologist Mark Thompson, author of Who should you have sex with, a compatibility workbook based on his years as a researcher with match.com and Yahoo. Try Thompson's tricks to determine whether he's even worth the effort. Ask if he dreams of climbing Mount Everest The more a risk-taker a brutha is out of bed - whether that means trying strange food (like curry) or bungee-jumping - the more kinky he is likely to be in it. Try teaching him something Anything: using chopsticks, playing Spades, or perfecting his tennis serve. If he's willing to learn G-rated stuff from you, he'll take directions naked, too. Let him drive you somewhere When he's behind the wheel, does he take his time and take in the scenery? Or is he pedal to the metal straight up the highway? Don't say you weren't warned!
