In the shower this morning I noticed a little lump on my labia. I hadn't noticed it before and it was sore to the touch. I have had cold sores from the herpes virus on my mouth in the past. None recently though. Could it have some how transferred? What else could it be? My imagination is running amok and I'm freaking out that it's a sti and DH has been cheating. I've called the go but can't get an appt until next week. What the hell could it be?
