Thanks for your reply!
I was wearing 6 and 7mm custom made tunnels in the last steps. Custom made because of the length i need.
I liked them very much. But for my actaul 8mm, the discs at the end of the tunnels will be 12mm.
And this is to much to hide them at work etc.
The discs from my ptfe plugs are just 10mm diameter and even with that, you can see my nipples through a shirt or even a sweater.
Of course, i like that. And sometimes i can see, that people are looking.
I am often curious about what they think
But, because of my job, i dont think that i can go further without pointing to much attention to my nipples.
What brings me to another problem:
The next step is a big step. Just think about the 10 (mm), is a big turn on for me
