My boyfriend and I have been having sex a lot and we dont use lubricant. Well last night I was dry and then in the shower this morning it felt like something was stinging/burning/swollen. I looked down and towards the bottom of my vuvla on the lip part (?) it looked like a small blister. I do have HSV2 but this does not feel like an outbreak; not in the usual area or the same pain. I looked online and it said if a woman is dry during sex it can cause friction which can lead to skin burning or irritation. Has anyone else experienced this?
