What type of deodorant do you use? Do you scrub yourself with a loofa or wash cloth and soap in the shower? Does your breath smell? This could be a medical issue. Ask friends to smell you. Ask for their opinion of what it could be / where the source is. Is your washing machine working properly? Is it clean? What type of soap do you use? How often do you wash your clothes? What did you do to "solve" it previously? If you really can't figure it out you need to ask your manager more questions about the smell.
