I had a friend try BO on me once. I think he really thought it would turn me on because I licked his clean arm pits a few times and swallowed his cum. He remarked once something about me eating his nasty cum.. So, I believe he thinks such to really be nasty. Then was the time we met and he didn't shower. It did NOT turn me on at all. I kind of believe he is a clean freak, literally. I went to his house many times but there were a lot of times I almost felt he didn't want to have sex in his bed because he didn't want to get his bed dirty. He came to my place once and the first remark when we walked to the bedroom was there was not one speck of dust on my floors. Good compliment but reinforced to me what I thought about him being a clean freak. Not so bad of a thing I guess, but in the latter of our friendship I don't remember him taking me to his bedroom at all. It was like he just couldn't bear it.
The remark about nasty cum.. I guess for a clean freak it might seem nasty, but I don't see anything nasty about it. It can have a pungent smell sometimes, but to me isn't nasty.
BO is another thing though.
