Now anytime I have sex and that pressure point is tampered with I receive horrifying pains? The pressure point is on the inside of my vagina towards the back.

I take it you have regular sex so pain from normal first event is out so but could have a sist there that got iretated by rubbing off the shaft of the penis or your Virginia is dry and is tearing tissue inside your Virginia so the best thing to do is to give it a rest for a week or so and see is it any better or try a differn position that might not hurt as much often when sperm is in the Virginia it can burn inside like acid and is very sore after that hope it some help

It could also simply be the head of his penis hitting the back of the vagina. When you're not aroused the vagina is really only about 3 inches long. When aroused the (if I remember correct names here.. ) cervix pulls back and the length grows. So, a large sized penis could hit the back. I know I have trouble doing "doggy style" with my boyfriend because it feels like he's hitting my insides after a short while. But any other position is fine. If I'm well aroused nothing hurts and that should be the same for most any woman I'd imagine.
