You have a good job and money. Why would you restrict your dating range? Younger chicks might be into you, go for it. And don't preface it with "I hope I don't come off as a creep but..." either. Do you man. Your current gameplan isn't working right? So why not see if someone 24-29 is interested? You aren't a creep, you're relatively normal, and you're pretty established in life. You have things going for you.
