Since birth

hey all
since the birth of my daughter 8months ago i have been unable to have sex with my husband. He says there is no room for him to get in so to speak
before baby we where fine but now we cant. i really down at the moment about it.
waiting for appointment with doctor so they can investigate, i can only think that when they stitched me up after they stitched to tight or something they shouldnt have.
Anyone else experienced this?,,,,,,,
