I have two questions, seemingly unrelated.

Women like a good smelling man..........besides shower and deodorant, obviously, what are some good colognes some of you guys use. I need to grab a bottle and start using. Also, do you just apply cologne when going to the grocery store or....when is acceptable?

and

I have resting dickhead face. So i know in public, i look pretty unapproachable. What can i do to at least try to appear half way approachable.

you can say smile. I have to fake my smile to most people (strictly talking a random person who may smile at me). Im not mad (which people assume), but i dont just go willy nilly smiling either. Any advice??
