After the Brandi belle vagina depth measurement video, we found a video where russian girls were measuring their vaginas. From the video, it is difficult to determine the level of arousal. From that video, we understand the importance of arousal to get the maximum possible vagina depth. In fact, it is exactly the same issue than penis. The flaccid size is not relevant in the context of sexual intercourse. The relaxed vagina depth size is not accurate in the context of sexual intercourse.
Here is the vagina depth size results from the video:
Candy: 14.5 cm (5.7 inches)
Carla: 11.5 cm (4.5 inches)
Irma: 19 cm (7.4 inches)
Anja: 17 cm (6.69 inches)
Lada: 18.2 cm (7.1 inches)
