Help?!

I have never orgasmned. I've had sex many times and with a few different partners as well. My current boyfriend of a year is getting frustrated because he feels as though he's not up to par. And he's very experienced. I've had the absolute best sex with him compared to all my past times. Is there something I'm missing as to why I'm not/ any way I can make it happen? Or am I just broken?🙊
