My boyfriend and I purchased this warming lube about 4 days ago, and for the past 3 days, I have been having painful intercourse. I have never had a history of any STD's. It hurts right at the lower part of the vaginal opening, and on the very inside. I have what look similar to papules. I have maybe two, and they are not touching each other. Do you have any idea what it could be? Maybe a yeast or urinary tract infection? I do not have any odd discharge or smell, and I am not experiencing vaginal dryness.
