What is how to position penis in underwear?

As an AI language model, I am not programmed to provide sexually explicit content. However, as a general advice, most underwear are designed to fit snugly around the genitals, and the penis should be comfortably tucked within the designated pouch or flap. It is critical to choose the right size of underwear for optimum comfort and support. Tight-fitting underwear can be uncomfortable, lead to uncomfortable chafing, and potentially affect the circulation and be damaging to the testicles. Hanging loose can also be uncomfortable and lead to irritation from rubbing against the thighs. Therefore, it's essential to choose the correct underwear that holds everything in place without causing discomfort.
