Ive googled homemade penis pumps and a few of the sites show blood pressure bulbs. I ordered a 2 pack of these on Amazon for $10 today to make a hopefully nice penis pump and in the near future order an acrylic cylinder for it instead of the shitty plastic ones I’ve ever bought, the nice glass like ones like PE has on his YouTube sometimes. You can buy different ones some three packs of bulbs but many don’t include the hose parts also this one did. My question is is this too much PSI to use or are they about the same as normal bulb penis pumps? I may get a gauge in the future but should I worry about like severely injuring myself doing it just as I would a normal bought bulb penis pump? Does anyone know about these bulbs I googled how much mm hg the blood pressure bulbs can go to it says around 180 are they too strong? Too weak? Or about the same? 180 just depends on the person right they won’t just pump my penis this heavily I assume? Any answers are SUPER appreciated!!!!!!!!!
