Your penis functions on blood pressure.
The brain sends signals to your penis, which
causes vessels to become engorged with blood.
Your heart pumps that blood.
When problems arise during this process,
the penis can go prematurely limp because
vessels cannot sustain the pressure for as
long as you’d like.
Further complications can include inability of
the penis to reach a full erection.
You want to make sure your circulatory system
is working at top shape.
Basically, what’s good for your heart
is good for your sexual health.
