Sophia Loren once said, “Sex appeal is 50 percent what you’ve got and 50 percent what people think you’ve got.” Sure, it’s easy enough to offer oh-so-humble pearls of wisdom when you’re one of the most iconic sex symbols of all time. (Sophia Loren shrugging off her sex appeal is like a socialite playing coy as she clutches at her million-dollar necklace: “Oh! You really like this old thing?”) But she has a point: sexiness is subjective — which makes compiling a list like “Boston’s Sexiest” awfully tough. Still, somebody has to spend hours surveying the city’s many attractive specimens (le sigh). And we think we’ve found a lineup of lovely, lust-worthy locals who represent a broad range of sexy styles. They all have different looks, different personalities, and different personal and professional backgrounds, so there’s no doubt you’ll find someone on this list who leaves you smitten. But they also share a common “it” factor: an impossible-to-describe spark that sets them apart and lights our fire. Are they each unique? Absolutely. Are they all sexy? One hundred percent.
