Here is the thing. I'm from a foreign country, I'm an alien here so the culture is significantly different than here in the US. It's a very less common thing for the previous generation to wear TWs, and the briefs selling there usually don't come with white color. Instead, the equivalent "dad's briefs" in our place are the navy blue briefs, white briefs, as far as I remember them, I saw them more often with more well built guys so they're not a nerdy thing at all. Hence, I linked TWs with sexiness in my mind before when I was little. In terms of my dad's briefs I can recall one thing. Probably when quite young, like 4-5 yo? I liked a pair of cyan to greenish briefs of my dad's LOL, and I tried to put them on and obviously my waist was just too thin too fill them..😅😅 But I just remembered that I felt excited and nervous when I tried them on, I guess y'all have similar experience. Oh and just to mention, I found a pair of briefs sold online, which had very close color as in my memories of my dad's, in 2022. So without hesitation, I purchased them immediately and got them hehehe 😂😂😂

I attach the link to the other subredit for blue briefs as "dad's briefs" in our place, and that cyan briefs in comment session.
