Inability to burp

I’m wondering if anyone else here besides me has this strange and rare symptom. I’ve never been able to burp, I only remember doing it twice in my life and those were barely audible. It is only recently that I found out this wasn’t a normal condition and that most people actually do burp. All my life I thought it was normal to not burp and thought that those that did burp had something wrong with them. Even drinking a carbonated beverage doesn’t make me burp. I get very uncomfortable feelings in my esophagus which may be the burp trying to come out, but it never makes it.
