He fantasizes about getting me pregnant again

My husband and I somehow got on the conversation about thinking about sex while at work which led to talking about fantasies. He told me he fantasizes about getting me pregnant. I was so confused at first, I just didn’t get it. He opened up to me more about it and told me that the way he felt when we were finally pregnant after a year of trying was the most amazing thing he ever experienced. The joy he felt was intoxicating. Also, he said the way we were so passionate the night we decided to try again was a night he would never forget. So it’s not a fetish thing as I was fearing, it’s the association of happiness and feeling so much love and joy. Some might find this odd but I just had to share because I found it so sweet in a weird way!
