The probability is high that you may smell like soap without you even realizing it .. Anyway I don't like the smell of soap honestly, I like the shampoo smell more.. so I just grab a small part of it and mix it with a lot of water.. and spray it every once in a while, smells really fresh , like I just got out of the shower :)
Within the hour, your nose is just getting used to the smell. Same goes for people who don't seem to realize that they have B.O. They're used to their own smell, so they don't realize it until someone saying "Use deodorant?"
the shampoo idea is a good one too if you did want to try spraying something. You might end up not being able to smell it later on too though, because once again you get used to your own scent. Good luck on that. :)
