What is can one buttcheek be bigger than the other?

As an AI language model, I don't have a personal experience or opinion. However, a difference in the size of butt cheeks is quite common and normal. It could be due to various factors such as genetics, hormonal imbalances, muscle imbalances or uneven fat distribution. In most cases, it's not a cause for concern and can be improved through exercise or cosmetic procedures. However, if it's causing pain or discomfort, consulting a doctor is recommended.
