the two most common causes of perineal or genital numbness is compression of the nerves in your spine (called as cauda equina) or compression of the nerves in the perineum itself. only sensory loss is uncommon but still possible in cauda equina syndrome (ces) since it is more commonly associated with other symptoms. compression of nerve in the perineum typically occurs in cyclists. i will suggest you to go to the closest er (emergency room) urgently. you need to be evaluated to reach the correct diagnosis. they may also order an mri for you to identify the exact site of nerve compression since the treatment varies as per the site of compression. delay in treatment may make the symptoms irreversible. for further information consult a neurologist online --> <link>
