Not really. The vagina is highly elastic. It can expand from the size of a little finger to that of a baby’s head. During intercourse, the opening of the vagina is normally not too small or too large for any penis because it is really a "space" that is surrounded by muscular tissue and will adapt to most size penises. The vagina distends according to the width and size of the inserted penis.
