Male and female bodies produce natural, and different, smells. Genetic women do not sweat as much as men and therefore do tend to smell a bit sweeter for longer. So how do you overcome this?
Make sure you shower thoroughly and use a good anti-perspirant/ deodorant to help to mask any unwanted male odours.
Top that with a female perfume to make you smell more attractive. You don't want the smell of the perfume to be overpowering. Just spray a couple of squirts into the air and walk through the mist.
TIP:
No amount of perfume is a substitute for a shower!
