I've always and forever worn conventional briefs. However when I was teaching in a tropical country for 2 years, I got so hot and steamy (temperature-wise) that I started getting skin problems, especially between the legs. Fungus infections become rampant under those conditions. I was forced to switch to boxer briefs. It really did make a big difference in skin health and comfort. I even acquired a fungus infection in the nails of one hand (the scratching hand) smile
