How can i make a penis pump with home made items?

Oh no!: Please don't experiment with your penis this way. You may injure yourself with a homemade gadget.

Do not do it: See a urologist, do not experiment as you may cause yourself great injury.

Here are some ...: Penile pump has taken 4-5 decades to be designed, tested, and evolved to the current form as the device to rehabilitate ED after trying behavioral modification to adjust to reality, lifestyle change, the use of PDE-5Is, etc. in collaboration with urologists. So, though it's nice to be imaginative and creative, do not try for this matter. More? Seek pro-counseling.
