Gosh, it's great hearing all these stories. This is how I imagine my labor experience - an intimate, loving moment between 2 people who are bringing a 3rd life into the world. I'd love to kiss, cuddle, have orgasms, etc., with my partner while in labor. After all, this is how our baby was created - between two people being intimate.
Of course, I might feel differently once it starts. But, for now, I'll continue imagining it as a very intimate, sensual moment.
