Smells are just smells, my dude. They don't have a gender. If I want to smell like roses, vanilla, or coffee fruit it doesn't make me laughable. If my wife wants to smell like leather, tobacco, or Armani Code it's not a problem. Transgressing norms is good. Gender is a construct, and it changes frequently. It is not static, immutable, or necessary for our survival. In light of that, I'd be happy to see gender-neutral or "feminine" aftershave. If I liked how they smelled I might be inclined to give them a try.
As a Marine, I'd be pretty amused if someone were to insist that I were somehow less manly for it.
I agree smells don't have a gender; they aren't a living soul. In my un-important opinion, scent has specificity among men's and women's aisles for obvious reasons. Some guys just arent into Chanel No 5 guy, cucumber or roses and stuff; I definitely get that because I'm one of them. Can't really call a dude gay because he's wearing a pink shirt, ya know? Haha. No judgement here though, 'Dev! (KNIFE HAND)
