How can I tell my brother that he stinks? - t.i.a. more condition_symptoms

My younger brother (now an adult) is always the worst body odor. All notices, but nobody wants to say something, because he is so sensitive. It stank of puberty and is used to it (of course, always run to her room and screaming), but the smell is not just untolerable. How can you a stubborn but sensitive to clean without hurting him? TIA
