sexual frustration

Every time me and my boyfriend have sex he always cums. Me on the other hand have only came once, and it was from oral. When ever we're doing vaginal he always cums and I never do. Afterwards he's happy and tired and I'm stuck. Sexually frustrated due to my lack of climax. What do I do. I've tried to tell him but he either doesn't get it or just doesn't care and I'm tired of my kitty being frustrated at the end. What do I do
