Chastity cage coming tomorrow

I’m a bit worried about how this will fit me since it’s made of steel, while my last cage was plastic. I’ve always wanted a soft silicone one, but they seem rare in our country. So I went for a stainless steel chastity device with a classic design rather than the lion or other heavy styles—a birdcage type that keeps my penis locked up for long periods.

I did have some issues with misuse on my previous cage because I used to watch porn while wearing it, which led to painful moments. It was like every time my dick tried to stay erect, this chastity cage would deny it. Hopefully, if the device fits me well, it will provide that denial of orgasm without causing complications in the upper part of my penis or the surrounding muscles.

Anyway, hoping for the best! Anyone with a birdcage please share what helped make the process less painful.
