Dry Labia- TMI

Sydney
So last night I got frisky with a guy and he was using his hands pretty rough on my labia minora. At first I thought I was just really sore from it, but I later realized it's actually dry there now and is sore in the dry areas. Do you think it's just dry from how rough he was? And what can I do to help it- if I should do something? Maybe leaving it alone to get better would be best? I have no idea! Lol
