How can I get harder erections without, "DRUGS"?????

Here are some ... Erection and sexual intercourse are the process of very heavy mental and physical drainage. To do well in them, one has to possess enough energy and ability to consume and drain. As men age, their ability to restore the emptiness of energy slowly impairs usually after 30. So, the only way to perform something in its best is after having a full mental and physical rest with half empty stomach.
