There's a difference between "needing" something and being addicted to it. A person would not fault another person for needing to eat, but a person can be addicted to food and be a compulsive over-eater. However, if you starve someone, they will become more and more desperate for food - which is why it's an effective torture technique.

Obviously sex is not needed as much as food. And some people are completely uninterested. But it is a hunger and it does increase over time.

The way I feel about it is this - just as a homosexual person shouldn't try to date a heterosexual person because they're sexually incompatable, a person who is uninterested in sexual activity shouldn't try to date someone who is. It might not be easy to find an eligible asexual person, but it's not easy to find a good partner in general.

You may decide for yourself, but if I had a partner who didn't want to have sex with me, no matter how honorable I am, I'd probably end up cheating or being miserable or both.
