There are many reasons for erections being non-existent. This could be for medical reasons or even depression. Penis pumps will definitely help solve these problems. They create suction and allow more blood to flow temporarily into the penis which aids a stronger erection. When penis pumps are combined with the use of a cock ring results will be at their best. There are also vagina pumps that are used to improve feeling and sensitivity when used, and nipple pumps that enlarge nipples and make foreplay more enjoyable by improving sensitivity in the breast area.
