He may not want to be rushed/pressured, but he has to understand that his desire to have extra time may cost you your (plural) chance to have another child. I'm sorry to be harsh, but it's true. Or it may cost you tens of thousands of dollars in fertility treatment.
Don't wait. Don't wait. Don't wait. I wish I could say that to everyone in their 30s who's waiting for just the right time. I started hemming and hawing about it when I was 32, started TTC right after I turned 33, gave birth to my first (and maybe only) at 36, after 3 IVFs and one loss. You just don't know if you're going to get lucky, and I wouldn't gamble with something this important.
