Initiating Sex

As

What are some way you ladies initiate sex. I have always been real shy about it. Ive been with mt fiance for 8 years. And we used to fight about me not being so forward about it. This was many many years ago. But now im more of a woman and i am also 22 weeks pregnant. I just want to be forward and sexy. So difficult for me to do. Why?? Its so fustrating. I go to bed wanting it so badly but he doesnt even know cause i just act like he supposed to know i want it. 😥
