For about the last month I've experienced extreme discomfort when performing coitus and it almost always bleeds and follows a very painful stinging/burning feeling. I'm terrified of going to the doctor but the internet hasn't really provided any reasonable answers as to what I could be experiencing. The labia minora looked like it almost had a canker sore which was pretty weird. I've only ever had one sexual partner and as far as I know he's only had one (me) as well.
