If it's your girlfriend, then who cares? Just tell her how you really feel. Everybody has preferences for everything, that doesn't mean it necessarily has to be a fetish if you just say "hey to be honest I kinda like the unshaven look better, would you be okay trying that?" I've only been intimate with two girls: The first one preferred being 100% shaven, but when I told her that I liked pubes, she was okay with letting it grow out a bit for my sake. And the other girl already had a bush so it was no problem, but I was still upfront about my preference and she appreciated that she didn't need to change her shaving habits to make me happy. Neither of them thought it was weird or got on my case for preferring one style over the other, because I'm pretty sure everyone realizes that to have pubes is just the default state of the adult human being, so of course some people would accept that as normal over the alternative.

said, if it's someone you've just started seeing, don't bring it up right away. Let her do what she's comfortable with, and present herself in the way that makes her feel confident and beautiful, then ease into preferences and fetishes together later on once you've become more comfortable showing each other your bodies. Pubic hair and the lack thereof is a completely reversible thing, it's not like if you had a distaste for tattoos or piercings or something and wanted to speak up about that immediately. So bide your time, you're not losing out if you just play the waiting game for a while.>>2277513
Not only that, but as I'm sure has already been brought up countless times, having pubic hair is factually more hygienic than not, because not only does it act like a net that catches and prevents a lot of foreign substances from entering the pussy, but shaving (and potentially cutting) makes your skin more susceptible to infection.
