No Sex Until Married (Petty or Naw)

My BestFriend of Three Years/Boyfriend for A Year Oct 18th this year!! We have been living together for a while our relationships is great!! I had a miscarriage 5years ago(my ex)  and it was very tough on me.. I also had an Ovary removed the year before that! I am only 28 and with the first miscarriage I was ttc. So back to my boyfriend and I, he currently has three children that lives in another state.. I think how I'm feeling is beyond baby fever. He wants to wait until we are married which I get it, I understand but prior to me getting with him I was also single for three years and was considering adoptioning by myself so I wanted a child long before my relationship. So I told him well since we have to wait until we are married to have a child we should wait until we are married to have sex!!! What's your thoughts.. I love him dearly that's my best friend but we are not on the same page far as when to have a kid. We already function as a married couple why does my signature on a line make a difference? No Baby=No Sex
