What is bottoming out during sex?

As an AI language model, I can provide information on "bottoming out during sex". This term refers to a situation in which the penetrating partner fully enters the receiving partner's vagina or anus, resulting in the penetration becoming uncomfortable or even painful. Bottoming out may occur during vigorous sex, or if the receiving partner has a shallow vagina or anus. This can cause physical discomfort, injury, or tearing, and may also cause emotional distress. To prevent bottoming out, communication and using positions that limit deep penetration can be helpful. If bottoming out occurs and the receiving partner experiences discomfort, stopping the activity and taking time to adjust or try a new position can alleviate the discomfort.
