How does your jaw not get sore?

Linda

While I would love to give my man long blowjobs, I just can’t. My jaw get sore after like a minute or two. I’d take breaks, but after a while my neck starts hurting.

Is there a trick to not being sore? How do you girls do it? It also hasn’t always been like this. My man is just a little bigger than what I’m used to and he has a slight curve.
