I am aromantic. You do not need professional help as it is not an aversion reaction, it simply is. As sexuality is fluid, so is romantic attraction. I am romantically attracted to no one, never have, never will be. And that's okay. That being said, that doesn't mean you can't have the things you listed.

I was in a partnership (basically married) with another aromantic person for several years. I know three aromantic couples who are married, and one has a child, and they are happy as they are.

Aromantic does not me "I do not feel love" it just means "I feel love differently" and there is nothing wrong with that.
