About the sore clit thing... overstimulation and stimulation in the wrong place can do it. I mean if you were both drunk, how do you know he was doing it right? I would stop having sex for at least a week and see what happens. If it's still sore after a week or two then I would think about seeing a doctor. Have you even looked at your own genitals to see if it's red, inflamed,etc.? Do you an STD? Please consider a period of abstinence if you have these issues.
