It was scary as hell putting my junk into the pump device. And using the hand pump to squeeze out the liquids time gave me fear as I could feel the suction pulling on my groin. It was such an interesting experience training my junk to superphysiological levels and I am excited to do this every day as part of my self-improvement masculinity journey. So much so that I even bought a 2nd pump right away (HydroExtreme5) to try a fit that was closer to my size.
