when you say "put to anything meaningful", are you reffering to your family and friends? maybe your agressive tendencies are a way for you to take control of a situation before the the spotlight falls on you and your insecurities and shortcomings. In some cases, the person who needs to take control or demean other people, do it because they are so uncomfortable with themselves and their own personality that they will take it to extremes to keep the attention off of themselves. or like the post above me said, you just take your dominance that you feel and display in bed to other parts of your life because there is no one in your bed to get your aggressions off on. I dunno, if that makes sense.
