I am also 17 and like fresh non heavy scents 1. YSL L'Homme (light, fresh, elegant, can be casual or suit and tie, has a apple juice champagne feel, its also lightly sweet in the end but in no way heavy and more fresh than sweet to me. My all time favorite). 2. Acqua di Gio (generic, extremely popular but no denying how good it smells).
Others would be Nautica Voyage, Polo Blue Sport, Versace Man Eau Fraiche, Lacoste Essential Sport, Cool Water and Tommy.
