Blood flow is everything
An erection is basically hydraulics. Blood goes in, a valve closes, it stays in. Anything that narrows or stiffens your blood vessels over time, smoking, high cholesterol, high blood pressure, sitting down all day, shows up in the bedroom long before it shows up anywhere else.
- Cardio, 3 times a week: even brisk walking improves blood flow measurably within weeks.
- Cut the smoking and vaping: nicotine narrows blood vessels, full stop.
- Watch the saturated fat: what's bad for your arteries is bad for your erections, they're the same plumbing.
