Emotional during sex

I (23) have regular sex with my partner with no problems but one thing I find is if a position allows him to go too deep and he hits my cervix, it’s like my body goes into panic mode and I start to cry.

It hasnt happens for a while but happened again last night, it only seems to occur during deep penetration, as soon as it hurts I feel like I’m in fight or flight and can’t control it and need to stop. I’ve been sexually active since I was 16 and this happened with a previous partner too around that age. Is it hormones and overwhelm or do I just have an emotional vagina lol? Does anyone else feel this?
