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 a suction and allow more blood to flow temporarily into the penis which aids a stronger erection. When penis pumps are combined with use of a cock ring results will be at its best. There are also vagina pumps which are used to improve feeling and sensitivity when used, and nipple pumps which enlarge nipples and make foreplay more enjoyable by improving sensitivity in the breast area.
