Hello, and Welcome (says another relative newbie!).
I suspect you've been lurking for a while and you already know this monster thread in Male Fragrance Discussion with a summary by Jonty about halfway down page 31...
Cool Water seems as good a place as any to start.
If you already have a 'girl of the moment' you could try taking her on a 'sniffing expedition' to find out which colognes 'work' for her on your personal body chemistry...
Otherwise, with a bit of imagination, you can use your entry into this hobby as a way of 'making yourself known' to the other half of the population of this planet.
Feel free to send me a PM if you want me to spell it out for you...
