It's long but kindly go through it all.

So guys I'm a 19yr old male who's never shaved his under arms b4 simply because while growing up I noticed that adults who shave their pits usually have the skin there looking rough and dark and disgusting so I decided that I'm never doing that till I'm rich enough to get the best razors or to afford getting them waxed. So recently I've discovered that my pits sweat a lot although the hair there is so little & never smells because I take my bath regularly & I've only ever used deodorants once which was a gift and was a spray type.

So I want to start using deos regularly but I do not know the best one to use between the roll on and the spray type considering the fact that I don't shave. So it'll be great if u guys recommend the best option for me.
Thanks.
