Oddly enough, I've found thongs to be the best undergarments to keep the twins dry. As an added bonus, they prevent swamp-ass by giving the sweat a way to escape.
Gotta go with cotton or wool, though. Synthetic fibers just don't cut it. I hate recommending name brand products, but after a ton of wasted money on Chinese brands on Amazon, Jockey thongs have performed the best. There's also a Czech woman on Etsy who makes them out of Merino wool, but they're like $30 a pair.
Source: I have hyperhidrosis (I pour sweat for no reason despite being in good shape), and sweat induced psoriasis so keeping my scrotum dry is of the utmost importance.
Okay but for real if anyone here is still using dryer sheets, stop, and go get some dryer balls. Way way better, they last forever so you don't need to keep using them, and they fluff up everything. I've had the same ones for 6 years or so now
I think mine are about 8 years old. Still work great.
For those who don't know, fabric softener and dryer sheets work by leaving a waxy coating on your clothes. This does make them feel a little bit softer, but also makes them TERRIBLE at breathing / wicking away moisture.
Ever think your towels just suck? Try not using softener or dryer sheets, they'll be good again.
