Hello,
It looks like trauma to the clitoris. For such trauma, do not use any cosmetic products at the sites.Also wear cotton undergarments.Application of mild corticosteroid cream and oral antiinflammatories like ibuprofen/acetaminophen are also helpful.If the symptoms are severe then it will be best to consult a gynecologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Rough sex will make her breed. It does not necessarily means it has been torn. Next time you have sex try using a lubricant. It can also mean that she is not lubricating enough by the time of intercourse. Good luck
