What effort do you put in to turn him on? Maybe he'll lead by your example. Try watching some porn with him. If your not comfortable with this, try watching the porn by yourself at first. This will not only get you aroused, it will give you great ideas! When your ready, watch it together. Tell him that the both of you are gonna copy what they do in the movies...you'll definitely get your orgasm and then some!! Let me know how you make out. Best of luck!
