What if

Just reading through blogs of other people that are suffering from infertility...I have a great respect for those that are so eager to have children and have a family that they are ready to turn to adoption. I have not thought that far ahead in my journey, but what if I was not able to have children of my own and what if I ultimately did not want to adopt? I understand that adoption would help a child without a family, but is it wrong for me to not have adoption as an option? I feel a little bad. If the hubby and I could not have our own children, would it be wrong to just enjoy each other's company? If we decided to just travel the world and live the way things are now, would that be selfish? Are there other infertile couples out there that tried to conceive, were unsuccessful, and just eventually lived life without adoption? I am not 100% certain on how I feel about adoption as an option. I suppose I have a lot of reflection to do in the event that we can not conceive. Hmmm...
