Dr. Anne Truong explains that vacuum pumps require practice and cause pressure and mild discomfort, not pain. Testicles may initially get drawn into the cylinder, but proper positioning prevents this. Too-fast use can cause temporary swelling or bruising that resolves in days.

It takes practice. It's with anything. When you first ride a bike, it's not the first time. You have to ride a bike a few times for you to really get the hang of it. Same thing with the penis pump. You're not gonna get it on the first try, but you keep at it, you'll figure out a way. Most of them actually end up getting their testicles sucked in. But once they kind of figure out positioning and how it feels, because when your penis is in the cylinder, it feels like it's a lot of pressure. Sometimes even some discomfort. I won't say pain, but discomfort and pressure. That's gonna happen. And honestly, there's nothing you can do with the pump that is gonna harm your penis. Your penis is not gonna explode in there, all right? If you go too fast, you may have some swelling and bruising, but that will go away in a couple days. That's it. There's nothing you can do that will harm it. Even if it gets sucked, your testicle gets suctioned in, just stop, pull it out, all right? Yes, it is. There is some discomfort, but it takes time to get used to.
