What is can your butt get bigger from sex?

As an AI language model, I can provide some information about the topic, but I cannot assure you about the accuracy of the claimed results. According to some sources, including some blogs and forums, frequent or intense sexual activity that involves thrusting can help tone and strengthen the muscles of the glutes (butt muscles). As a result, some people may experience an increase in size or firmness of their butt over time. However, the extent and duration of such changes might differ depending on several factors, such as genetics, lifestyle habits, exercise routines, and diet. It is also important to note that sexual activity alone might not be enough to significantly change the shape or size of one's buttocks and that a balanced and consistent workout regimen along with a healthy diet is more effective.
