I think I have an idea of what it is, but just in case, how do you do it properly? When do you do them and how many times do you do them. Last night after I jelqed i just grab my dick and squeezed it for 10 seconds. That's not base squeezes is it?
It sounds like a manual constrictor. From the titular discription, you hold your penis tightly where it meets your abdomen. This keeps blood from leaving yoru shaft so quickly and keeps your CC and CS stretched for a longer period of time. I use a cable clamp to get the same effect.
