cant orgasm

I have been with my boyfriend for a long time and he makes me feel amazing, emotionally, physically and sexually. He took my virginity and I am head over heels for him. We always have great foreplay and sex but I can never orgasm. weve tried toys, different positions, porn, even masturbation cant get me off. Its really frustrating because he feels bad and i really want to feel a pleasure i feel like im missing out on. i love him and i love making love to him regardless but im really hoping to feel an orgasm and have that connection between us. he tries so hard so i think it might be a problem with me. anyone have any ideas/suggestions/ advice/experiences?
