I'm in the love hairy pussies camp! I liked what another poster said about 1998. I still found a lot of hairy pussies in '98 (when I was single), but I will admit that was when I first noticed shaving as a serious trend. I guess the reason why I am so fond of hairy vaginas is because I was the probably part of the last generation where that was the norm. I first started regularly 'hooking up' (as we used to say in the 90's) in '95-'96. And I can tell you they were all hairy - maybe some were a little trimmed. The reason I say "regularly hooking up," is because I had a little luck prior to that (maybe '93) but unfortunately, these two trysts were isolated. Suffice it to say, prior to '95, the two pussies I'm thinking of never came in contact with a razor or any other hair removal product. I loved it! I had been watching 70's and '80's pornos for years prior to actually seeing a live vagina, and I always thought it was cool seeing the guy spread the hair apart to reveal the delicious-looking 'fruit' inside. When I was lucky enough to see my first pussy in '93, sure enough there was that familiar triangle of brown hair partially shrouding those tender lips beneath. My constant porno viewng taught me just what to do. I parted the hair and labia and licked her clitorus and vaginal opening for half an hour.
As I became luckier and luckier and sex/sex play became a more regular thing for me, I would love when the carpet wouldn't match the drapes so to speak and it would be a nice surprise to see black hair down below on a seeming blonde. I even once hooked up with a brunette who had the most gorgeous muff of blonde pussy hair when I got her panties off.
I've never had problems with odors or "hair balls." As for odors, for whatever reason, the times I recall a vagina smelling foul were with shaved females. As for hair balls, like a previous poster said, that is not a problem if you know how to eat pussy. You use your thumbs and fingers. (Although I've never been able to resist intentionally licking the hair down there. And with practice you can do it in such a way as to avoid it from ending up in your mouth and down your throat.)
