So your thinking of using a DTR device but are unsure where to start.

To use the DTR or Retainer device some shaft skin is needed. The more shaft skin available the better.

Almost every man that restores starts with a CI 1 or 2 on average , Consider yourself very lucky if you have more than a CI-2 when you are starting.

Another option you will see is gripper choice, Grippers with holes are a little more flexible since there is less material

Its seems to be a 50/50 with people using grippers with or without holes. so it really is just a personal preference.

Manually stretching the skin is also another way to start.

Loosening the skin is the first step in the process and this normally takes only a few days to a week making using a restoring device an easier to do.

I had trouble when I start to restore for the first time. It can feel awkward at first. You will get erections when trying to attach a device. This happens to most of us. After a few days my body became used to the idea of having something attached to it. The erection issue when installing a device diminished as will the awkward feeling of having something attached to my penis.
