Yes, it can feel very good! In fact, now two and a half years post-robotic surgery, erections with my pump can be supplemented by actually bringing on an orgasm - odd, when (of course) nothing emerges! But can give your pelvic floor muscles a special little workout! But generally, as has been said elsewhere, the main purpose is to give the penile circulation a good boost now and again, and that's what the pump does, no matter how often or seldom you use the device.
