Suited or non suited doesn't matter. AQ isn't that strong of a hand. Did you know that you are behind 22 preflop? I think most everyone agree's that your raise preflop was way to big for both the strength and number of players in the hand. Like I said before, you need to consider what they might have and bet accordingly. If you price an opponent in, they will call everytime chasing any draw. This is why being able to assign ranges to your opponents is so important.
