I don't think 'having sex' means what I think it means

Last night I was so caught up in a story, I sat behind my computer reading until 04.30 am. I still managed to get up at 06.30 and work all day *g*, but needless to say my brain was a bit fried. In a jettlaggy way. (Thank you artistic_sillie for the rec to the first chapter of that mega-fic)

I'll give you the link to the whole damn story later, but since it brought up some questions ( I want to talk to you about SEX first )
