Is it normal to have a protrusion on the upper wall of the vagina?


Hello Dr.
Tsao: I have never touched a woman before, so I am not familiar with the internal structure of the female uterus.
A few days ago, while I was helping my girlfriend with foreplay and inserting my fingers into her vagina, I noticed that when I touched the upper wall of the vagina (the side towards the abdomen), the inner wall felt like it had a noticeable protrusion (at least 0.8 cm in width and also about 0.8 cm in depth), resembling an "M" shape with rounded corners, with clear indentations on both sides.
I have seen some cross-sectional diagrams online that make me think the vagina should feel more like an "O" shape, so I am really unsure if this is normal.
When I asked my girlfriend if she has ever touched herself internally, she said she never has, which makes me a bit worried about her.
Additionally, when I slowly withdraw my fingers (1 to 2 fingers), she says it hurts.
Is it normal for her to feel pain during the first few times? What should we do if it continues to hurt after multiple attempts?

It's completely understandable to have questions about the anatomy of the vagina, especially if you or your partner are not familiar with it. The vagina is a complex structure, and its internal anatomy can vary significantly from person to person.
When you mention feeling bumps or protrusions along the upper wall of the vagina, it's important to recognize that the vaginal walls are not perfectly smooth. They are made up of elastic tissue and muscle, which can create variations in texture and shape. The "M" shape you described could be related to the natural contours of the vaginal walls, which can include the cervix at the upper end, and the surrounding structures such as the uterus and bladder.
In a healthy vagina, it is normal to feel some irregularities or bumps, especially if you are touching the upper wall where the cervix is located. The cervix can feel firm and rounded, and it may be more pronounced in some individuals than others. Additionally, the vaginal walls can also have natural folds and ridges due to the presence of the vaginal mucosa, which can create a textured feeling.

Regarding the pain your girlfriend experiences when you withdraw your fingers, this could be due to several factors. If she is not accustomed to penetration, it is normal for there to be some discomfort initially. The vagina is a sensitive area, and if she is tense or anxious, it can lead to muscle tightening, which may cause pain. It is crucial to ensure that both partners are comfortable and relaxed during intimate moments.
If the pain persists after multiple attempts, it may be a sign of a few potential issues. One possibility is that she may be experiencing vaginismus, a condition where involuntary muscle contractions make penetration painful or difficult. Another possibility could be related to insufficient lubrication, which can lead to friction and discomfort. It’s essential to communicate openly with your partner about what feels good and what doesn’t, and to take things slowly.

If the discomfort continues, it would be advisable for her to consult with a healthcare professional. A gynecologist can provide a thorough examination and help determine if there are any underlying issues that need to be addressed. They can also offer guidance on how to make the experience more comfortable, including recommendations for lubrication or relaxation techniques.

In summary, feeling bumps along the vaginal wall can be normal, and the discomfort during penetration can be common, especially for those who are not used to it. However, ongoing pain should not be ignored, and seeking medical advice is a good step to ensure everything is healthy and to address any concerns. Communication and comfort are key in any intimate relationship, and taking the time to explore and understand each other's bodies can enhance the experience for both partners.
