Seriously, when someone compliments on the cologne I'm wearing it does kind of feel that person has made my day.
But yeah, mainly the compliments come from the ladies... only a few guys ever ask what I'm wearing etc... Most guys won't compliment saying "that's nice" even if they do like the smell of your fragrance because they might think they're giving out the wrong impression that they're gay or whatever. I do get compliments off guys but they're normally quite close friends or from my family... but you shouldn't worry, some people might be too shy because they might not know you enough but it doesn't mean to say they don't like what you're wearing. If you want to impress the ladies I find A*Men and 1 Million are the biggest compliment getters from my personal experience.
