Jaw lockup while giving head

Mackenzie

Sooo this may be kind of strange and unusual.. but the other night I was giving my boyfriend head and when I went to close my mouth my jaw wouldn’t shut!! I was so scared! I just kind of rubbed my jaws and it closed.. normally my jaw kind of pops when I yawn and open my mouth wide but it’s never locked up before. Should I be concerned? Is something wrong with my jaw? Is this a normal thing that happens to other females!!? TIA💙💙
