If you’re going to remove hairs from different areas, wax it so eventually it’ll stop growing back and thin out in that area. Chest and back hair aren’t a bad deal unless you’re a total yeti/Bigfoot looking dude. In that case, I’d make sure to trim it. Always take care of your pubs hair. Don’t shave that shit, but keep it trimmed. No girl wants to suck some dudes dick and get an impossible mouthful of pubic hair.
In general though, be proud of your hair, it’s a sign of your testosterone. Just keep it reasonable, one doesn’t want to look like a caveman.
