Body odor?

So I don’t have bad BO but I feel like I might have a smell cause when I go around ppl they rub their noses but no one says I smell I’ve asked ppl who I feel would tell me the truth. And they was like nooo you don’t girl. I know I tend to get musty under my arms sometimes, I don’t wear perfumes and stuff cause a lot then don’t mix with my body chemistry well I don’t think so. I want ppl to be like ohh you smell good. But ntn tends to really give me that kind of reaction idk
