initiating sex

So me and my boyfriend have been dating for about 11 months. For the first 6-7 months we had sex everyday that we saw each other (usually every day) but now it's like we barely have sex at all. We talked about it and he did say that it bothered him that I have never initiated, which I totally understand. We have sex maybe 2 times a week, which for both me and him is just not enough and I do want to have more sex but I'm not sure how to initiate I'm not sure if I'm afraid he might say he's not in the mood at the moment and I might get embarrassed because I don't deal with any type of rejection well or what it is but I want to Be able to initiate and to make him feel like I am attracted to him which I definitely am, it just gives me a bit of anxiety. Any advice?
