“Your parents were making love when they were making you”

My boyfriend passed away 7 months ago and I miss him so much. The first time we were in bed together, he said something that made me laugh really hard and while I was laughing he said, “Oh I’m so glad that I can make you laugh,” “Your parents were making love when they were making you.”

That’s not only the sweetest thing anyone has ever said to me, but it’s also the sweetest thing I’ve ever heard.

What do you think he meant and felt when he said this? I already know, but I just kind of want opinions on what he meant by that. I just miss him so much, he was so special. Like who would even think to say something so beautiful?
