Arm fit smell everytime it sweats.

My armpit is smells since teenage , once I wore my brother tshir . I tried everything to remove this sweat smell , many cosmatic and natural remedies, not disappearing, what is it , I don't understand. It's been 10 years since iam using nevia underarm roller , otherwise I feel embarrassed around other people , it smell so bad , I feel ashamed . My husband also caught this sweat smell from underarm after wearing my tees , now I'm more embarrassed, I tried to hide this smell from many years . Will I ever get rid of this arm pit sweat smell ? It's only smell when my underarms starts sweating, even small quantity of sweat smell worse than any garbage, fishy smell. I hate it .. I always keep my underarm clean , tried best to keep it clean and healthy, my diet is healthy and clean , I use cotton dress , airry one . I shave, I don't know what am I not doing ? I drink lots of water , I do exercise, I eat fruits, vege,meats ,pulses to maintain my health .
