I would be suspicious of an infection. I would recommend avoiding sex until you see your doctor because the friction may just continue to irritate and cause pain. It could be yeast but it's best to get the correct diagnosis. If it is trauma from rough or dry sex, rest will allow it to heal. Once you attempt sex again, be sure to use extra lubrication to decrease friction. Don't worry too much - I would not anticipate anything serious.
