Easy to explain: It makes you sweat more and move less while sleeping. I'm glad you're eager to make a change. You're still young and probably vigorous. Head down to the local gym or sports center, let others see that you're working hard on your body, and they'll accept you as a friend and support you in your body transformation. A lot more is at stake than just the skin in your groin and neck. Best wishes.
