This is the most common term used in this area yet there is no concise definition on it. One thing I like about Kevin Samuels was that he had a specific criteria in order for a person to be defined as a HVM. I do disagree with him on the criteria, though.

A high value male is one that has an abundance of sexual options.

That's it. That's my opinion on who is a HVM.

What is your definition of a HVM? Have you ever met any? Any popular figure that meets your criteria?
