Tell him that if he does not like what is after all a normal smell used by nature to attract males then he should move on,there are plenty more males I am sure will find you attractive in all aspects,if he still protests then tell him it's "holding hands only then" see how that alters him.
Or go to a doctor if its not serious thatz his prob
Take a shower before you see him & eat more healthy fruits.
I would suggest to clean your area very good or spray perfume everytime you see your boyfriend.
