I wouldn't say it rules out anyone. Men who are attracted to older men find it persists well into late life. Even men your age may be looking for someone older than they are.

Most men who seek older men aren't looking for a sugar daddy, although some are. Most of these men I correspond with want softness in the relationship, more emotional intimacy, a body with some substance. They feel secure in these relationships but often are more financially secure than their older partners.

After reading your essay, I'm convinced you have these "Daddy" qualities, even if object to the word.
