There are actually some people, including doctors, who believe that erections happen because blood rushes to the penis. Can you believe that? LOL! Some people should go back to school and re-take their biology classes!
The only way to get an erection is to exercise the penis using weights like the one pictured. It’s like building muscle in your body and arms; you need to life weights regularly.
So, if you want to turn your penis into a massive beast, get yourself this willy exerciser. Don’t listen to those silly people and their crazy blood theory.
