Wearing cock ring all day for girth growth?

I just got into PE recently, however due to workload, I don’t really have time to do consistent exercise yet. I read articles and posts saying that I can increase the girth by just wearing cock ring all day. I found a setup that my penis can stay semi-erect the whole day (no flaccid state). I don’t experience any pain or discomfort either. My penis got a bit dark/blue, but don’t seem to be significant bad. So I just have some questions about my status:

- Does wearing cock rings all days actually help with increasing girth (hopefully length)?
- Is semi-erect state healthy? Should I wear the cock rings all days? Or should I take break every xx hours?
- How long should I expect to see any progress?
- Is the girth growth depend on the length growth? I’m kinda giving up on the idea of PE for length, since from what I looked up on articles and forums, there is no good way to work on the length all day while at work, I’m kinda afraid girth won’t grow unless length grows longer.
- Is there any supplement I can take to speed up the progress?

I know some of the questions are pretty basic, but there are lots of info out there and it’s hard to pin point what works and what not.
