I find the super duper hairy, like looks like a wookie look not visually appealing. Probably not appealing for touch either, since I like the feeling of bare skin. No personal experience with someone that fuzzy thus far. Back hair is not my favorite, and my partner does not like it on himself either. I help him keep it clipped/shaved to where it is not really noticeable. Some chest hair, tummy hair, leg hair, arm hair, whatever? Human body tends to lean a bit fuzzy for most folk and I like the more genuine seeming look than someone who waxes/shaves everything into non-existence. More important is how soft it is and if they use conditioner/something along those lines so it is soft. I am a very cuddly, touchy feely person with the folk I am involved with.
Person I was with wanted to wax/shave/whatever, rock on, but please keep stubble phase to a minimum. Person I was with left everything au natural, rock on but keep it soft/touchable. I really do not have that much of strong feelings one way or the other. It really is down to what makes the person happy. If my partner decided they liked having some back hair, great, I will let it be and more power to them. I am not a person who tries to tell a person to change their appearance to please me. I was attracted to them how they were and it is not my business to change 'em. If they want to try new things, that is fine too.
Like I said. Low key about this shit. Still find it odd that complete strangers are being queried, but whatever. My original answer holds true, the above in this same post is just a more detailed ramble about it.
