My vagina hurts and when i wipe it feels like i been cut but there no cut there 

The skin in and around your vagina is extremely fragile and can break very easily, chances are that you are experiencing broken skin almost like cuts or grazes and you probably won't be able to see it. Your skin should heal itself over time like what your body does with normal sores, just try keep the area clean to avoid infection and try not to wipe too hard. Also tell your boyfriend when he's being to rough with you, foreplay is meant to be pleasurable not painful.
