Why do I not want to have sex, like ever?

This is probably because you are not in the mood for sex, which is totally fine. Not everybody has a strong sex drive, which is what we call someone's desire for sex. Among the things that can affect a person's sex drive is their age, their state of mind, how they're feeling, stressors going on in their life, not meeting the right person, their past experiences, not wanting sex, being asexual, etc....the list can go on. If you do not want to have sex, you likely have your own reasons or preferences that explain it. But, this is also one of those things that do not always need an explanation – in other words, if you don't want to have sex, that is A-OK!
