When we got married, we got a lot of pressure from his side of the family to start having kids right away. At the time, I was still in school, and I knew I wanted to switch jobs and get settled in a new job first. It got so bad that on my 30th birthday, my SIL gave me literature about infertility after 30, and the chances of having a Downs baby going up (like she should talk, she had my nephew at 26 and he has Downs). My husband had to talk to them and tell them that if they want any relationship with me they better back off. This wasn't just my decision to wait, it was ours - he completely agreed.
This was also about the time we were going to start trying, and it's when we found out that he wasn't producing sperm, which is something he probably had his entire life, nothing to do with age. His parents were the first people we told about the problems. They backed off for awhile.
Now, they tell us about every teenage mother-to-be in the county, or every problem mom-to-be they know of (that they think of being a problem) thinking we can just step in and adopt. Adoption doesn't quite work that way.
My mom would bring it up, but nothing like the pressure we've gotten from his folks.
So, just about everyone close to us knows we are TTC, except his parents and sister. We told them we aren't having any kids. We thought we'd finally tell them when I'm pregnant enough to show, maybe from the delivery room if we're lucky.
