When you think of sex, what first comes to mind? Are you full of excitement and desire? Or are you immediately in dread? Does thinking about sex make you feel anxious? Are you annoyed? All of these feelings are created by your default sex thoughts. Do you like what you are thinking and feeling? Do you like what is happening for you? If so, then great! No need to make changes. But if you don't like what is going on for you, or you have a desire to see things differently, then you might need to work on those default thoughts.
