Sex life

I am so unhappy with my sex life. We have sex once a week, and sometimes that once a week will only be oral and no penetration, or I won't orgasm leaving me unhappy knowing I have to wait a week. He says he doesn't want sex every night because he wants time to want me but my sex drive is so high I want it all the damn time! His other excuse is that he's tired. I tried masturbating but a dildo never feels that good to me and nowhere near the real thing. I'm sick of always going to bed sexually unhappy. I love my SO to death but sex is important too! What the hell do I do?
