Why do I only attract older men?

I'm 33 and I get hit on and asked out by men in their mid-40's and older. Even in my late teens and early 20's, not a single guy close to my age ever asked me out or showed interest in me. In a way, I'm flattered 'cause most of these older men are successful professional, good-looking, decent men. But the age thing really bothers me. What is it about me that I can't attract guys my age or close to my age?
