[Advice] Hygiene Questions for Men

Just a couple of questions:

First off, I have a lot of chest hair, like i have the happy trail that pretty much connects right up to in between my nipples, and then spreads onto my Pec's (not a huge amount there) I also have the hair rings around my nipples. So should I shave / get it waxed? i personally like it, but I've heard that a lot of people say they think its gross.

That leads into my second question, which ties into the first. The same people that said that chest hair is gross also say that any pubic hair is also gross. I normally trim my pubes. I would think it would look really messed up if i shaved off all of my pubes, just to have my happy trail end abruptly where my pubes should be.

and third questions, completely unrelated to the other two, do you guys where the same scent of cologne / deodorant each day or do you have multiples that you use.

TL;DR - Should I shave chest hair and pubes completely (I currently trim), And how many scents of deodorant and or Cologne do you use.
