Pumping can be a good way to help with erectile dysfunction although if you suffer from sever E.D you should probably consult your doctor as even a pump may not be able to help.
You might even want to look at your diet as that can play a big part in erection quality.
E.D can also be a sign of low testosterone so exercising and intermittent fasting could help too.
Anyway, how can a pump help?
Pumps like the Bathmate use vacuum pressure to gently draw blood into your penis.
This stimulation can help you to get an erection.
The best pump to try is called the Bathmate and you can get one from here.
