We have been married for 11 years. I had abad smell issue. My wife rarely share bed with me. We both sleep on different beds.
What Islam says about it?
brother its a very normal issue. and this problem is cureable. if you visit a good doctor i am sure bad smell issue will be resolved.
you must try to solve this and you can share the things you are feeling with your wife. so she can understand your problem.
try to cooperate.
May ALLAH solve your problems brother.
