Sex isn’t pleasing???

I need advice/help. I’ve been with my boyfriend for a few months. He’s my first serious relationship. I lost my virginity to him and we’ve had sex probably like 8 times, but it just doesn’t feel like much to me. We’ve tried numerous positions and doing foreplay, but I CANNOT orgasm with him. I have orgasmed from masturbation, but not from him vaginally, orally, or from him touching me. I also can’t orgasm with him even when I’m touching myself. We also got a vibrator to try. It felt good at some points, but again, I just couldn’t orgasm. He loves having sex with me and never has a problem finishing, it’s just difficult on my end. And yes, he is aware it’s been difficult for me as we’ve communicated on the topic. Also, if it matters, he isn’t huge down there, but is probably slightly under average. Finally, I’m aware that not everyone can orgasm vaginally, I just want more pleasure from the sex we have, even if it has to be from him touching me a certain way.
