Any proven methods for Penis Headglans stretching

I am really interested to get to know any methods that I can use to stretch my penis head/glans with!

I have been working on a device for couple of weeks now, but since I have never done this before I don’t know yet if it will work!?

If my device will work I will post pictures of it!

I am looking for anyone with real interest in the subject to post their findings, methods, links, ideas etc etc.

Hopefully we can discuss this in more dept!
