A problem many beginners have when they’re just learning how to give head is that they clench up their jaws, which of course makes the jaw really sore after only a small period of time.
The two best tips I have for avoiding a sore jaw are the following:
1) Relax Yourself. Just remember to relax yourself and remember to take a breather once in a while. Whilst you’re taking a short break, just keep jerking him off with your hand. No one is expecting you to keep going non-stop like a robot.
2) Don’t try to apply pressure with your jaw. It’s not what it’s for. Just lube up your hand and use that instead, it will feel equally great for him.
If you just try to relax yourself and remember to start using your hands to produce the pressure, instead of your jaw, your sore jaw will disappear soon enough.
