sex in biblical times

I'm in a church after a party. We are tidying up. Mum and Joe are there. I’ve left an organ key down – the tone is sounding out, and so I go to turn it off. On the way I see James and Marie and go over to them for a chat. We talk about what life must have been like in bible times… I question something they tell me, - a question we are discussing about what sex would have been like in biblical times.. surely it would be totally different to nowadays…
