How to seduce my boyfriend

So i have being with my boyfriend for 3 months now. And i have noticed that we only have sex when he wants to and not when i want. I brought it up and told him about my obersavation. And he said its because i haven't being able to seduce or turn him on enough to want to fuck me. Mind u he suceeds everytime in seducing me. He just knows the right places to touch. But i never seem to get it right with him. Anyone has tips or advice for me?
