This aspect likely produces negative feelings that fester under the surface of what could otherwise be a very good relationship. The problem is that you don't treat each other as equals when it comes to sex or work or anything else you try to accomplish, either as a team or on your own. Your partner usually tries to take the leadership position, telling you what to do and how to do it, and that can inspire rebellion at the least, or even anger.
Haven't they learned yet that you like to be in the lead? Your sexual expression is similarly stilted; you rarely want the same thing at the same time, but you're both insistent about having your own needs met. Guilt and repression could become a part of your routine as a couple; you get excited about something and your partner tries to repress that enthusiasm like water dousing a flame. You two focus too much on respectability versus rebellion, outrageous behavior versus decorous comportment. And you always seem to be on opposite sides of the fence. The friction and tension mounts until you're both able to abandon any pretense or hope that you have about controlling the other's behavior, or directing them in how they use their time. Otherwise, you find yourselves being rather passive-aggressive, or even openly aggressive. Arguments and cutting remarks set the tone between you two unless you both make the effort to treat each other with respect.
