Is there a way to open vessels in your penis to alway max blood flow to increase penis size?

Be healthy: Stay healthy. Don't be overweight, exercise, eat well, maintain good nutrition, don't smoke, drink or do drugs. These are better than any medication out there. Good luck.

Low penis blood flow: If you think you have low penile blood flow, an angiogram of the arteries of your penis can give you a definite answer. You would have to pay for it, unless your physician can give you a diagnosis covering its cost. At age 25, what makes you think you have it?

See answer: Though the quality of one's erection is largely dependent on the health, integrity, and status of the penile vascular system, penile size in the flaccid state is largely independent of blood flow. Healthy lifestyle, heart-healthy diet, proper exercise, and regular , appropriate, sexual activity are the best ways to maintain optimal erections and blood flow to the penis.
