meaning - Understanding "that" as in this statement


If I only say something as below without further more explanation, will a native speaker understand me?



He may be sexually dysfunctional, lately he can't do that his best. That's why I am here to help.



If I said it out loud and stressed "that", would you then ask me what is "that" ?
