I'm a newbie to this forum but have some experience on this topic... first lets call it what it is,… Guys, especially us Big Guys are sensitive and seldom talk about Chaffing, Jock Itch and Yeast Infections … yes, I said yeast infections. Women can talk about them all day long but Guys get them as well. All have physical and mental ramifications that could and in many cases do diminish one’s desire to get in better shape. The good news is that all are also easily controlled/ avoided with the right gear and diet, compression boxers and corn starch play a big part with all physical activity. Compression boxers do not have to be expensive, I have Under Amour but my $10 Walmart specials work just as well. Make sure they fit tight and keep them updated as you lose size; loose fitting compression boxers can end up riding like a thong in no time at tall… Corn Starch, powder if you prefer but Corn Starch is Corn Starch and I get mine from the baking isle… No added fragrance or other ingredients and it keeps me just as dry.
