Just thought I'd post a quick update.
I've managed to get a pair of C-IN2 briefs with Trophy Shelf - very appropriate
they are much bigger up front than any other briefs I've worn before and they do accommodate my balls very comfortably. The material is also very soft. I've not had the chance to wear them for a full day yet under my suit as I've been commando all holidays!
I have taken a couple of pictures and have attached these.
Thanks for all the comments and advice, I'll keep you posted with and developments
Andy
