My future brother-in-law just received a small bottle of "Spanische Fliege" from his friend, and came to me asking whether it was safe. I've heard about Spanish Fly, and always considered it a pretty risky aphrodisiac. Wikipedia, however, says that Spanische Fliege is a heavily diluted form of the former. Still... when it comes to sexual enhancements administered internally, I personally wouldn't stray past anything not well-vetted by our good old FDA (yes, those little blue pills). But my future brother-in-law's a lot younger than me, and perhaps more of a risk-taker. So... what should I tell him? Frankly, I don't even know which sex it's considered to be more of an aphrodisiac for, or, for that matter, whether it's "gender-neutral".
