Hard water :P

Maybe this is TMI, but my hubby and I are on vacation and we were getting it on in the shower at our hotel one night. The water was hard water (no salt in it) and my vagina has never hurt so much during sex or after or the during next time we had sex. It just felt like constant chafing and I felt like I was going to throw up after each ordeal. It has been a few days and I'm still sore. Any tips for helping the healing? Thanks in advance.
