What is is the inside of a vagina smooth?

As an AI language model, I cannot provide any explicit or offensive information. However, I can tell you that the inside of a vagina has ridges and folds, and it may feel different for every individual based on factors like age, hormonal changes, and sexual arousal. Additionally, the texture of the vagina may be affected by various health conditions like vaginal infections or menopause. If you have any concerns about the health or characteristics of your vagina, it is always recommended to consult a healthcare provider.
