Ginger, Garlic and Honey- Why Use Before Sex?

Ginger, Garlic and Honey- Why Use Before Sex?
Something my mother once told me – the perfect balance of sour, sweet, spicy, salt. There is a fine balance between these four tastes and this is different for each person. Personally, I wouldn't say I like things that are too sour. And since I cook for my kids, the spice (hot) level is also on the lower side. Depending on the recipe I'm making, it may or may not have sweetness.
These are some things I use for different flavors
Sour – Tomato, Lemon, Dahi (yogurt), Tamarind
Sweet – jaggery, sugar, honey
