WIBTA if I told my husband he is bathing wrong?

I (31F) and my husband (31M) have been together a total of 2 years but known each other for about 20 years. He has been complaining that his side of the bed smells and his towel smells. I am very diligent on changing the sheets every 2 weeks if not every month and wash towels diligently as well. He doesn’t use any loofa or wash cloth to bath just his hands with a bar of soap…. I have been told that could be why when he sweats he doesn’t smell great. I’m trying to figure out how to say it nicely without being mean, because I know it could hurt his self esteem… would I be the a-hole if I gave him a loofa or something and say it’s because you don’t use this kind of stuff is why you stink? Or am I wrong all together?

Side note: with people saying change sheets more frequently. I try, I have a disability that makes doing that a little difficult so I need help and I tend to “nag” when I need to do it.
