What's "Spanish Fly"? My girlfriend says that if you take it, you get really horny.

Another great myth! People have been looking into substances that can get a person turned on sexually for centuries! These things--like "Spanish Fly"--are called "aphrodisiacs."

The only thing that so-called aphrodisiacs have in common is that they don't work! And no studies have shown any drug to increase a person's sexual arousal and desire. Even something like Viagra helps a man who can't get an erection get and keep one--it doesn't give him the idea that he wants to have sex. That has to come from him.

Now, everyone is different--different people get turned on by different things. For some people, smelling their partner's perfume or cologne can turn them on (even if they smell it on someone else!). For other people, eating particular foods can turn them on so much that they want to share them with another person during sex. This does not mean, however, that fresh strawberries are an aphrodisiac or that you should run out and start spraying your perfume or cologne at people!

The most powerful sex organ we have is our brains. There is a vast array of ideas and images that can turn us on sexually. But alongside the myth that there is a "love potion" that can make someone fall in love with us, no pill or medication can make someone feel horny.

And the worst part of this myth is that people sometimes will take these pills and slip them into other people's drinks or food to try to get them to want to have sex with them. And aside from the fact that you should never take medicine that hasn't been prescribed to you, it really shows that the person who's doing it is trying to take advantage of another person.
