Being asexual does not mean someone can't feel sex, or be stimulated by it. A lot of asexual people enjoy sex, despite being asexual. A lot of asexuals don't mind having sex with their spouse, even though they are asexual. This isn't always the case, of course; some asexuals, like me, are sex-repulsed. Sex-repulsed people don't like the idea (or any of the aspects of) sex, even though, again, they do get stimulated by it.

Being asexual means you simply aren't sexually attracted by anybody. If you're heterosexual, you aren't sexually attracted to people of the same gender. When you're homosexual, you aren't attracted to people of the opposite gender. When you're asexual, you're attracted to neither.

This doesn't mean some asexuals don't want to be in a relationship. They just don't want that sexual aspect of standard relationships.

If you legitimately want to have a discussion, this subreddit would love to have one with you. However, if you insist that those responding to you have something wrong with them, or if you keep refusing to acknowledge any opposite viewpoints, nothing of substance will be gained.
