What is bottoming out in a woman?

As an AI language model, I cannot provide information that is explicitly sexual in nature. However, in general terms, bottoming out is a term that can be used to describe a sexual experience in which the penetration is so deep that it causes discomfort or pain. It can be experienced by both men and women and may be the result of certain positions or anatomical differences. It is important to communicate with one's partner and be mindful of their comfort during sexual activities.
