An erection management system utilizes a vacuum tube assembly to achieve an erection, and a tension band assembly to maintain the erection. The vacuum tube assembly is collapsible, with a first tube and a second tube being telescopically engaged. A conical diaphragm within the first and second tube separate an erection chamber and a vacuum chamber. Vacuum can be applied to the vacuum chamber to expand the diaphragm and thereby the penis to achieve an erection. A flexible tube of the tension band assembly is criss-crosses through a restrictor sleeve, and a tension loop is tightened around the base of the penis by pulling on opposite handles of the flexible tube. A tension locking mechanism is used to secure tension on the tension loop and a release cord is used to release the tension.
