Discovering Your Tastes Takes Time
There is a huge variety of food cultures and subcultures that take a lot of time and immersion to get involved with; the same is true of sexuality cultures.
There Are Tools to Make Things Easier/Better/More Pleasurable
Food preparation can be highly advanced, and can involve a lot of gizmos and gadgets, including "single job" tools. The same is true for sex. Of course, both things can be accomplished simply as well!
It's Personal
It takes time to understand what foods and what type of diet work best for you. The same goes for sex; we all have different needs and desires.
Not Everyone Will Be Adventurous
Some people are picky or closed minded about their food, and don't want to try eating or making anything new. It's the same with sex. Some people stick with the first things they learned, and never stray beyond them.
They Play to Our Senses
Sex and food can both access all of the senses and, when done well, are both deeply sensual experiences.
They're About More Than the Sum of Their Parts
In the same way that food is about more than nourishment, sex is about more than reproduction.
Expertise Isn't Everything
You don't need to be a chef to know about and have skills when it comes to making food. You don't need to be a sex educator to know about and understand sex.
Food and sex are two of the greatest pleasures life has to offer. They're ingrained into our existence as human beings. They make up a huge part of culture and experience, and are entwined with how we think and how we interact with the world. In many ways, the way we think about them is interchangeable.
Why do you learn about sex, and in what ways are food and sex similar for you?
