Burping
I'm a girl and I want to know how to burp or belch.
Just swallow air and quickly form your mouth into an "O" shape.
Well, I'm a girl too, and I love to burp. It comes pretty naturally to me, but swallowing air or chugging sodas help. I guess because I can belch on command, its very easy for me; and I can usually let out some really loud/long ones anytime I want. Right now, if you want to learn, I'd start by just drinking a lot of soda or eating fast; just to warm you up; then you can start on swallowing air and burping on command.
Hope this helps.
