I need to lose weight is there an effective safe way to do it where it's fast but still healthy and also in losing this weight will my penis lengthen

If only that easy...: Body sculpting sounds promising (& there are gimmicks &diets that promise you their products can do this), but the only way to effectively spot-reduce unwanted tissue is to surgically remove it. The "pear" body type preferentially stores fat around the hips; "apples" store it around their waist. Calorie count, exercise -- but no quick fix otherwise. Good luck with second part of your question.
