High sex drive!

I was a virgin when I got with my boyfriend....we had an incredible sex life, and still do.....but it's less and less often. He comments on how beautiful and hot I am, or how horny I make him buuuuuuut, we hardly ever have sex anymore! He on the sly asks for blow jobs occasionally but never really seems to put in be effort into me. Every other aspect of our relationship is incredible (just moved in together and love it!) He's caring, kind, respectful and is perfect in every way. But I'm starting to feel unattractive and unwanted...and losing confidence fast. Surely my virginity hadn't fueled our very awesome sex life. He didn't even know until about two months in! What should I do? I'm going crazy!
