With a penile implant you can have sex as often and as long as you want. This is because after an orgasm the erection does not go away, but the penis remains erect.
Only by pressing the release valve of the pump the fluid returns to the reservoir and the penis returns to the flaccid state. As the penis itself is not replaced, sensitivity and the ability to orgasm and ejaculate are not affected negatively affected in any way. An implant can thus bring back the pleasure of intimacy and sexuality.
