Yes, as long as it smells good & isn't overpowering. Some old ladies wear perfume & you can smell them from a mile away. My girlfriend wears a really nice perfume, unsure what the name of it is though.
Somewhat. If I can still smell where you've been five minutes after you were there, you need to back way off on that sh*t, as it is annoying and just makes me think you have some sort of disgusting B.O. problem.
eh. I hate perfume that you can smell from distances. if the girl is close then its all good. but if she's like 8 ft away that's overkill.
so if you use the stuff, don't use the whole bottle xD...
