Several factors affect body odor and whether it is pleasing or not.

1st, Chemistry, which is unique to each of us. It is a special makeup of our body's chemicals, pheromones, ect..

2nd, Just like one perfume/cologne smells differently on everyone it is this same "body chemistry and unique pheromones that causes the differences in the smell.

Doctors will also tell you that it's these unique smells that attract the opposite sex. It's our divine makeup that sends invisible messages to others.
