Is it normal for it to hurt when doctors press your stomach?!

Every time i go to the doctor and they check my stomach i always feel pain when they press down. Its not extreme pain or anything like that but it hurts. Its kinda like a sharp pain. Im pretty sure its not the doctor because ive beento different doctors and i would always feel this pain no matter where they push down. I dont know if this is normal or what because a doctor hasnt told me that theres something wrong with me? i didnt say anything because if there was something wrong with me then the doctor would have said something but they didnt so i was asuming it might just be normal?
