Questions: How did you know you were asexual? How do you know you’re asexual, when you haven’t been with anyone yet?
My answer: Well… You’re right. I haven’t been with anyone. And I guess men, women, and non-binary people are great, but have you ever been single and enjoying a delicious spaghetti squash meal? What about garlic cheese bread, or a good pizza made with the right dough and toppings? What about a Coke 0?
Have you ever enjoyed planning your own day? Enjoying your own free time? Not have to worry about “performing” for another person, nor asking some guy or some gal or some non-binary person permission to hang out with friends? Have you ever enjoyed your own TV shows without a dude?
How do you know your straight if you haven’t done any of that?! How do you know your straight if you haven’t really been single?! Go try being single, it’s awesome. You’ll never go back to being straight again!
