I'm curious.
I read it quite often on here and I'm really curious as to what is meant by it.
"I met this man on POF. We went on a date... after the third date we went back and had amazing sex... I haven't heard from him since. Why?"
or
"I've been seeing this man, I know I've got to end it, but the sex is amazing..."
or
"I've been seeing this lovely man and the sex is amazing"
That type of thing. And I've just read another thread where an ill fated encounter was described but where the sex was "amazing".
I've had a fair bit of sex. Of varying degrees of quality. But this phrase, when I read it on here, always makes me wonder, "I wonder why it was amazing. What does Amazing Sex mean?" I've had sex that was good/bad/indifferent/lovely - but I'm not sure it's ever been 'amazing'.
I suppose I just wonder what I'm missing out on! 
I've been here ages, I NC regularly. I could have posted in sex but I didn't reall think it warranted it. I'm not looking for specific details
