I got to admit that I'm a 19-year-old male and I never really use deodorant.
Why would you never use deodorant?
I usually use the perfume my mother buys for me
It's your right to live how you want, but you still have to be considerate of others. Having body odor is not pleasant and can make people sick or repulsed by you. You may find it hard to get a date by not practicing normal hygiene.
I am thinking of wearing a shirt that says \"I have BO\" and doing a demonstration at school.
I wouldn't really advertise the fact that you don't use deodorant. Like I said a lot of people are going to be repulsed by it. I think maybe you should try to get into the habit of practicing good hygiene, it would be beneficial for you.
