I just don't see the issue either way. Dating is for compatibility, the normalization of "putting your best foot forward" is not reflective of everyday life. But sure. Continue the trend that's led to a 50% divorce rate in the US and call me crazy 🤷♂️.
And to clarify, I've never at any point said to be unhygienic. There's a difference between hygiene and ritual and the cleaning regime of most people falls into the latter category and is actually, perhaps unintuitvely, damaging to your skin.
Your dating partner imo should also be comfortable with you as you are, not under any specific or special circumstances. It's not sustainable over long periods of time such as the decades you'll potentially spend together. Perhaps this is just the perspective of an old soul, but I've been around the block and I've found the more effort you put in outside of your normal self, the more likely you are to find out you're incompatible farther down the line than right away. I'm not trying to give an excuse to the guy who's not showered in a week or who absolutely reeks the second the walk in the room, but to pretend it's something you must do before a date and that going into it smelling natural is obscene is just investing heavily into a pervasive peacocking mindset that's caused everyone to be more shallow in their day to day. It's a side effect of the commercialization of personal health.
