It's not called "animal attraction" for nothing. Creatures great and small (humans included) secrete pheromones, chemical substances that oh-so-subtly stimulate whoever happens to catch a whiff -- it was only a matter of time 'til somebody bottled it. At Unique on Central, N10Z -- "Undetectable . . . undeniable . . . the world's first gay pheromone product" -- can be had, two ounces for a mere $39.95. What makes it gay? Apparently, scientists at California's Human Pheromone Science Institute have discovered the chemical makeup of pheromones that cause attraction between men. And as long as we're "enhancing," why stop with scent? Up the, uh, ante with the California Muscle thong swimsuit ("Look larger than life while at the beach or catching the sun"). Prefer to do your enhancing in private? The shop's online store is open 24/7.
