I've been married for 14 yrs this August and we dont have any kids....AND i'm a Pediatric Nurse LoL Plus i come from a huge Italian family where everyone has kids. I cant have children, but i always came up with excuses when people asked me "when are you going to have kids". I really didnt want to go into the real reason why i couldnt have kids..and personally, i didnt think it was anyone's business, but it always made me feel bad when they asked. People need to learn to think before they speak....they do not know what is going on in a person's life.
You should have kids when YOU are ready...not when others want you to..Just remember that.
