Actually, I do have some experience. Are you holding the shield right next to you? If you are, you can change your stance a bit. Hold the shield with your hands the way you do normally. Then bring your elbows right beside your breasts while holding your arms out a bit. Make sure that when you are standing, you have one foot behind the other with most of your weight on your back foot. Then your partner makes contact, allow yourself to fall back on that back foot and even step back if you need to. If that still doesn't work, you may have to hold the shield completely away from you to the side. If you're using it for kicks, you can hold it to the side with your arm bracing. Just be prepared to let it give when your partner makes contact. If you're using it for punches, you may have to get the smaller shields that you hold with each hand. I hope that helps some.
