Sorry if this topic is too personal or not appropriate for this site but I've noticed a very particular issue recently. When I kiss and get intimate with my gf if the act is hard (her lips push back hard and fast) then I get a immediate slightly painful pressure in my forehead and sometimes feeling a little nauseas. I've never noticed this until the past month or two so maybe my heightened anxiety is partly to blame but could hard kisses me subconcussive or concussive impacts?

I remember Mark saying a sub concussive impact would be like clashing heads on a football field so I don't know if this would be comparable or if someones lips could produce a similar force is they were trying to. I know this issue might sound banal but it actually is kind of affecting my relationship since I've had to distance myself physically from my partner in order to avoid kissing as much as possible (although it does still happen). Could it possibly be tmj related rather than pcs?
