Hey man I have no answers or solutions for you but I wanted to tell you that I have developed this problem as well later in life. It's all the same man. No matter what I do it always exudes a horrible, almost chemically pungent aroma. I bathe incessantly in the hopes of keeping it at bay, scrubbing the afflicted area with vigor and fury but it just doesn't make any difference. I just wanted to tell you that you're not alone and don't let this destroy your life. I read through some of the replies and am going to try aromatic deodorants in my underoos and maybe even the damn Vagisil thing. Hang in there. It's not just you.
