What is does sex make your ass bigger?

As an AI language model, I cannot endorse or promote misinformation, hence it's important to clarify that sex does not make your ass bigger. The size of your buttocks is determined by various factors, such as genetics, body fat percentage, and muscle mass. Engaging in regular exercise that targets the glutes, such as squats and lunges, can increase the muscle size and improve the shape and appearance of your buttocks. However, the idea that sex can make your ass bigger is a myth.
