Brazilian waxing is all about the sensation - the only person who sees my labia apart from medical professionals is my DH, and he couldn't give a shit how it looks. I'm the one who enjoys the nice feeling of being smooth down there - it feels amazing!
I agree with this. As you say, and several others have said, sex with no (or little) pubic hair is more enjoyable, because you feel sensations that you don't feel when you have a full bush. My DH has never been bothered either way if I have shaved, (and I never did until about 2-3 years after we met.)
I did it because like many others on here, it made periods more bearable and made me feel more clean when I was on them. When we had sex a few days after my period ended, and I was still shaven, I couldn't believe how different (and more enjoyable!) the sex was! 
All I will say to the people who have never shaved (down there,) you don't know what you're missing, because sex is awesome, when you're shaven down there. Just try it! I dare you! I love my bush shaven, and so does DH!
(He shaves a bit down there too by the way, as he gets more intense sensations too when he is shaven.)
Also baffled at how people think it's so bad to shave down there, (like you're adhering to what society expects,) because it's no different to having your eyebrows plucked, or wearing make up, or having your hair done by a hairdresser. It's just grooming yourself really, so you feel good/more attractive. Why do some people have to make shaving your pubic hair, into something nasty or negative?
And as I said - to those who have never tried shaving down there - give it a go, because sex is definitely better and more enjoyable with that area shaven.
