It just feels nice.
Like I like to wear extra flashy undies under neat my plain clothes and think "if all of our clothes suddenly disappear, I'd look the best among all of these peasants!"
And that is smart because in case of a car crash or if your building explodes (thanks to a suicidal neighbour who chose gas) you won't end up in the street in your ugliest pair of underwear like my sister's neighbours 17 years ago. We still talk about that sometimes, and that's the reason why she taught me to always put on nice underwear. (In all fairness, the explosion and guy dying were quite a shock, which explains why she remembers that of all things).
Shaving can be beneficial when your goal is to be clean. No hair means no hair to need to wash blood out of. Yes, ingrown hairs can be a problem. It's just noteworthy that not everyone who shaves does so due to appeal.

It makes you look, well... 14...
