Ok, what has happened is that you basically "pulled" a muscle. By stretching the vagina too quickly most likely, without giving it a chance to heal. Or, it could be that you are not lubricated (wet) enough when you are penetrated. Try not having sex for 2-3 days and then the next time you have sex make sure that you are very wet (lots of foreplay) you can also use a lubricant like KY (this won't hurt you). This should solve your problem. If you continue to have pain, please see a doctor. Sex should never be painful.
