Girls, hi! Can you please tell me if a narrow vagina creates problems during childbirth? I had an examination with a gynecologist, honestly, I felt pain and discomfort when she inserted her hand there. The doctor said that the vagina is very narrow. But I will say that I was worried beforehand that it would be painful and so on. Maybe I just squeezed my muscles out of fear? Now I'm worrying, could this be a problem during childbirth or better not torture myself and have a c-section?
