Could I be too small or just have vaginismus. If I feel down there my walls contract a little, even if I'm not trying/ if I'm not nervous, and if the walls don't contract it feels a little uncomfortable to insert my finger or fingers...and when my doctor did my check-up I contracted a little and it hurted really bad for them to check down there. Is it that I'm too small, just nervous, or does it sound like vaginismus?
