Hello Jeanna Marie,
This has happened with me in the past but has only occurred after a session of intense suckling and this was when I had met someone new and hadn’t suckled for quite some time so I guess over enthusiastic. I would say that after a few days the jaw ache went away so its certainly not something to get worried about…maybe take it easier and build up the intensity of the suckling, if thats what you like.
Its a bit like going to the gym as a new participant and hitting all of the equipment on your first visit…your gonna ache afterwards.
I prefer to suckle gently then stronger then gently and if I get jaw ache have a break, have a coffee then resume…build up slowly. Hope that helps, Barry.
