Here's the long and short of it:
I like au natural. But not all women are the same, soooooo...
Excessive: You probably don't like it either and feel self-conscious. Fix it so you feel comfortable, it's low-maintenance and looks/feels natural.
Waxed-bare pretty-boy: Step away from the mirror, get over yourself and get a new hobby that actually interests other people and isn't all about your looks.
If you are trimming or shaving this or that because it makes you feel more comfortable with yourself, you're a swimmer or bodybuilder or whatever, that's fine, but don't get obsessive about it or become more high-maintenance than the women you want to attract or keep.
Hair in places that men grow hair: You're a man, it's OK, we like it. Don't worry. Spend the time and money on something your female interest might care more about.
However... if you are with a partner and she has asked you to trim this or that back, it's not unreasonable of her to ask... just do it as long as it is within reason... and as long as she's willing to reciprocate when you voice your own preferences within reason.
The exceptions: Hair visibly growing out of your nostrils or ears: Ewwww! Unacceptable! Fix that! And don't feel like you're entitled to ask her to reciprocate by expecting her to wax her p*ssy bare, especially if she actually had to ask you to fix that! If she has something equally gross (gigantic hairy mole between the eyes or worse), you may gently suggest it would appeal to you more if she would fix it as well, and to help her to do so.
