What makes a city sexy? The first things that pop into my mind are things like lots of sun, sand, and buff physiques dressed in skimpy swimwear. But that's not really what this list is about -- instead we're looking at the American cities that don't necessarily look the sexiest, but feel the sexiest instead. Or, as Forbes (who compiled the list) says, feel the most "lustful." (Yeah, I should have called this post "America's Horniest Cities!")

Anyway, who do you think came out on top of the list? Forbes took into account things like contraceptive and condom sales in the nation's 50 biggest cities to determine who is having the most sex -- do you think a buff-beach-body town landed as #1? Think again -- good 'ol Denver CO is in first place, followed by San Antonio, TX and Portland, OR tied for 2nd. Surprised? I am, actually! See the rest of the top lustful cities (and let us know if you're lucky enough to live in one!):
