Sex life with boyfriend of almost 2 years- ladies help!

So, I’ve had the same boyfriend for almost two years and most of our relationship is great. However, my sex drive is substantially higher than his. I feel like whenever I initiate, I always end up getting rejected. He has talked before about his struggles with intimacy and for that reason how he usually feels uncomfortable when I initiate and wants to do so himself. This constantly makes me frustrated. We probably end up having sex once a week on average. I guess I’m looking for some advice, does anyone else have this problem as a straight woman where they have a higher sex drive than their partner?
