I have a 38 year old BFA male. Yes, he was very hormonal during his teens and early 20's. However, like someone else said, we never had to worry about eggs. My friend lost her Macaw to egg binding.
My Sam is not a great talker. But, he does talk a lot. Just in Amazon LOL. He says about 12 - 15 human words, but can communicate anything he wants in bird speak. I have had him all of his life, and never found him to be mean or nasty. Just acts like the intelligent motivated parrot that he is. If you remember that parrots are incredibly smart and have skills that we never thought about, you will be fine. Treat them like a small human and they will respond to you. They are not dogs, and cannot be disciplined like them. I almost have to reason with Sam, if you can imagine that! It has taken me all these years to learn about how to live with an Amazon, and I bet I am not finished yet. I would not, however, trade one single minute. It has been one of the greatest parts of my life to be allowed to spend time with this wonderful little person/bird. I hope you can say the same one day. Good luck. Anita.
