Another reason to wear what I call "come here girl" is because a woman will associate you with a sent, and will actually still be able to smell your scent and think about you long after you leave.
Women tell me this all the time, that after you left I could still smell you and was thinking about you. Or one of my girl friends told me I had your scent on me.
If you are seeing women for a decent amount of time, dont change too often, because you want her to think of you whenever she smells that smell.
ps. For all you dudes creeping, women sense of smell is way more acute then ours and yes they can and do smell another woman's perfume on you. Women will make sure they leave their smell on your on purpose if you are cheating with them, so always, always, wash before you go home, or once you get in. Make this a daily habit so when you out there is no suspicion if you are the creeping type.
