I wear cologne like twice a year, but when I do it's Adidas Deep Energy. It's really cheap too if you're also not into buying expensive shit, lol. I think it cost like 15 bucks or something like that. And...well...I think it smells good! Basically, if you've ever smelled the deodorant or body wash it's the same thing but a bit more subtle.
Otherwise I wear Axe Phoenix body spray everyday as a deodorant. I just like the smell and its pretty much the same thing as cologne, imo, except its more useful and doubles as deo
