If the toad poison doesn't work for you, then there's another horribly ill-conceived source of hope: Spanish Fly. Don't get freaked out, it's not really a fly, that'd be gross. It's just a beetle. A blister beetle. A beetle that causes blisters.
And here it is fucking... something
This legendary aphrodisiac is nothing more than ground up bug bits. What's more, the active ingredient of the stuff, cantharidin, only exists in quantities of about five percent per beetle; meaning many of their tiny exoskeletons have to be crushed to a powder to make just one shimmering, bitter tasting dose. The likelihood that each hit of Spanish Fly contains at least as much tangy insect as your average meal at Taco Bell is fairly high.
If you are willing to ingest this creepy crawling cocktail, be prepared for the results. Spanish Fly is not so much an aphrodisiac as it is a toxin that will give you a horrifyingly itchy inflammation of the genital area and a rousing case of priaprism (a hard-on that just won't quit). And who amongst us hasn't thought a night of passion would be made all the more exhilarating by the addition of horrible crotch itch and a raging poison boner?
This guy tried it. He loves it.
