Trouble orgasming

Ladies, I need help. I have only actually felt the buildup once, but the release didn’t really feel mind blowing or good. It was almost like I was just pushing something out. Is this normal? How can me and my boyfriend get to those mind blowing orgasms? Or how can I make my release make me feel great? Is it supposed to just feel like it’s being pushed out and it’s it? Or am I supposed to feel extra pleasure? And it seems I have a very hard time orgasming and it’s getting embarrassing when my boyfriend can but I can’t. Is there something wrong with me?
