I make most of my briefs
I have sometimes made my own knickers too. I found that commercially made thongs were too stretchy to grip my bum crack well and not big enough to take a full erection - I am only 6 inches. So I set to work on an old sewing machine bequeathed to me and made some out of non-stretch white nylon which is easily washable.
MANY years ago I was at a friend's house and we decided to go to underwear night at a bar. I was freeballing so he gave me a pair of Calvin Klein briefs to wear. We had a blast at the party (and that night after the party) and he gave me the briefs to remember "our first night together". I still have them and,even though they have been through a lot, I still think of him every time I wear them.
My brand is Separatec - has compartment just for the penis so you kinda get the feel of a cock ring. They are super comfortable as they have a line made out of bambo. There is also a slot at bottom compartment that you lift and you can pee without have to wipe it out.
Like Tommy John and Jack Archer at the moment. I love variety
I'm not hung up - pardon the joke, on designer brands at all. CUM fort is paramount. Colorful bikini briefs or panties, butt no thong / very uncomfortable for me. The skimpier, the better
