How Can Underarm Hair Be Grown?

I am almost 32 years old and have NEVER NEVER EVER grown a thick patch of hair under my underarms. I am really insecure about this and would love to know more information about my options for any type of procedure. This is quite serious to me it everyday is affecting me. I am married and my wife does not care, but I do. I just would love to have a full patch of hair under both my underarms. It would be a dream of mine. Thanks again for reading.
