what smells good depends on what you prefer …
but i can tell you that i like most scents by Androtics on me …
the way you describe your personality you should be able to benefit a lot from using mones …
you say you need an edge when out partying … what kinda edge are you searching for … as you have a girlfriend … bad boy .. 
could you imagine to benefit from mones in other areas of your life … for example at the workplace .. ?
and when you say you are looking for something for the more intimate encounters …
what about using your girlfriend some mones as well … no joke buddy … you´d be amazed .. it turns you into a beast ..
