So the past few times me & my SO have had sex the skin around the opening of my vagina has been mega sore during and for a few days after. At first I thought it was because of lack of lubrication so last time I used lots of artificial lube but no help, still as sore as ever. I always get slight soreness at the base because the skin always tears there but this is soreness all around. I think it might be a yeast infection because I had this symptom the last and only other time I had thrush but I'm not sure. I have got an increase in discharge and it's ever so slightly itchy but that might just be psychosomatic. Help?!
