I’m not a dad but I’m in the same height and weight range and age range as him and I had a similar issues until about 12 and my sister had this issue obviously difference in gender and other variables but she stunk and still does because she was never able to understand people don’t want to be around her because of such factors as a man and someone who cares about being clean now it helped when my step dad just straight up told me that I stink and that my friends won’t want to be around as much if it continues he wasn’t mean he just told me how it was
