I guess I had it all wrong...
I have always believed when it comes to sex (like many other things) it really is about quality over quantity, whether it be duration of time, number of orgasms, etc. If things are being done well, there is no need to watch the clock or keep a tally.
I still prefer it last as long as possible!
There are so many smart ass things I could say here, but I will hold off.
I can only say that the standard quality over quantity stands true here. Of course if one was in to trantric sex, where people claim to have multiple orgasms over multiple hours, both apply.
There was an unscientific poll on a news site I frequent that frequent agreed with this story.
I would include a link, but I can't find it. Damned dynamic content.
My generation called that "a quickie"
And when you have kids, quickies can be a godsend.
