Is sex still that taboo?

So the reaction of one of my friend's a while ago got me thinking. Is sex still taboo for most people? Are people still to embarrassed to openly talk about their sex life in normal conversation?

This thought came about a few months ago after having the followingconversation with one of my friends;

Friend: Miss J, why is there a tube of lube on your coffee table?
Miss J: WELL! I can't have sex at the moment because of the issues with my cervix so while *boyfriend* was watching the footy I decided to give him a bit of a rub and one thing led to another and hey presto all of a sudden there was lube all over my boobs and dick in between.
Friend: Wow, ok...
Other friend: *laughing hysterically.
Miss J: Haha well you asked me what it was doing out here so I told you...
Friend: Yeah but I wasn't expecting such detail!
Miss J: Well you know what I'm like, it shouldn't be surprising.
Friend: I will keep that in mind next time.


This friend has never really been one to talk about her sex life which I find odd, as me and my other friend talk about it openly...
Heck I even laugh and talk about it openly with people I have just met, especially when they make it sound like it's something you should be ashamed of.
I just don't understand this taboo that still surrounds sex, I mean cummon people! it's the 21st century!! People have sex and a lot of them enjoy it, don't go putting a downer on it.

I do respect that some people just think that some things should stay private, buuut I guess when it comes down to it I'm not one of those people.

So what do you think? can you talk openly about your sex life? or do you think it's just one of those things that should be kept quiet?
