Men have engaged in a variety of unusual practices involving their genitals, from inserting unconventional objects to attempting DIY modifications. Some have used items like pens, cables, or even live animals for self-exploration, leading to serious injuries. Others have tried self-surgery or extreme body modifications without professional guidance, resulting in severe complications. These actions often stem from curiosity, a desire for enhanced pleasure, or psychological factors, but they carry significant risks. It's crucial to approach such activities with caution and seek professional advice to ensure safety.
