We are in the beginning stages of adoption as a first choice also. I do have a medical history that could possibly make conceiving difficult, but still possible. (As far as we know!)
That said, it has not been a determining factor in our decision to adopt, and we have never 'tried' to become pregnant. No plans of it either.
Hubby and I have joked and said that there's nothing special about our genes that makes us feel compelled to pass them on. LOL.
But in reality, the roll of 'Mom' appeals to me the most; I am not concerned with having a biological connection to my child.
My mother has questioned my intent to adopt versus conceiving - it took her a while to wrap her head around it. She thought maybe I had some underlying fear of child birth or that she had flawed somewhere in her own parenting (not so.)
I think other people just assume that maybe we are unable. Personally, I don't care what they feel or believe, but will be happy to educate them on our decision when asked.
I was initially a bit concerned about what our social worker would say as well. We have yet to begin our homestudy, but I've been reassured by many couples that this should not be an issue as far as SW is concerned.
So nice to meet you all.
