I also have had my share of troubles with AA in the past and have therefore given these situations some thoughts.
First: what table image do you have? Since you are new to the game your opponents do not know this and therefore have to label you as tight until proven otherwise. The range of hands they can put you on would be something like AA KK QQ JJ and AKs
Let's look at this situation from the button and assume that he has put you on this range of hands.
For him to call he needs a premium hand himself. If however he has position and deep money he can also add medium and pocket pairs to his range. These are the ultimat trap hands and have huge implied odds

Given this information, the flop is a total disaster for you. You correctly make a potsized bet, but I would have let go of the hand after that.
