GF pounded too hard and long: Advice needed

I would like to ask for some health advice. My ex girlfriend and I recently reconnected and the sex was intense and relentless. But I'm afraid I overdid things pounding her too hard, too long, and too many times over two days, mainly doggy style.

I'm only an average 6in but her pussy is tight and she is small inside. I was careful to check that I wasn't hitting her insides or hurting her. Unfortunately three days on and she's still feeling sore, tender and inflamed inside. She says she can feel the tenderness when she presses her tummy just below her navel where my cock has been hitting her cervix.

Is this normal or a symptom of something more serious? How long will she need to recover? Is it just a matter of her getting used to me (again) and accommodating me inside her? Or do I just need to go easy and be more gentle? Thanks.
 
nothing to worry about. this is normal after a hard pounding and more so if you say she is tight and small. she should be good after a few days. ask her to do some kegel exercises. google it.
 
She will be fine, lots of fluids!

NASA has been trying to duplicate the durability of the vagina for decades, she's gonna be just fine. Give her a few days.!
Good job mate! Knocking the bottom out of it is a good thing
 
Agree with the other commentors...she should be fine. Will just need some time off. My wife got pounded by her bull for over an hour after not seeing him for a few months. Unfortunately for me, I couldn't reclaim her after he left - she was sore for a couple of days afterward.
