Tonic

Speaking of alcohol, if you're drinking a gin and tonic, it may be a double whammy on your sex drive. The bubbly liquid's slightly bitter flavor (that we hope you aren't too found of) comes from quinine, a naturally occurring chemical compound from the bark of the cinchona tree and a powerful painkiller. This analgesic effect suppresses the activity of the hypothalamus, the area of the brain that regulates hormones such as testosterone. Luckily, we’ve got soda water as a sexy substitute!
