You are not really satisfied with how you percieve yourself smelling. This can lead to these sorts of problems. You must train your brain to like what your nose tells you. Live in the now, stretch out your arms, open up your body language.....and so forth and then you might succeed.
More seriously though, like here in Sweden people are generally pretty introverted....don't start chatting with strangers barely at all unless it's like a party and so on..... And yeah you might want to wear more, like for me 3-4 sprays is the dealio, maybe 1 less maybe 1 more basically, depending on the fragrance. Maybe even a bit more but really I'd rather just re-apply if it's fading then. A bit subtle is preferable for many reasons, most of the time. And ya wearin it under clothes can screw things up..
