Penis Pump temporary gains

I would like to know if there is a way to keep a good erection coming out of a penis pump at least long enough for a good love session with the wife? Any help would be greatly appreciated.

The sure fire way is to put on a cock ring. I use an elastic cock ring that is actually a broccoli band. I initially found them in the grocery produce as they are the rubber bands that hold 3 stalks of broccoli together, but later found a place to buy them new on line.
