Does not wanting to have my "own" baby make me selfish?

My problem is though I don't want to do it myself. I don't want to be sick and pregnant. I don't want my body to grow. I don't want to feel my child kicking inside of me. I REALLY don't want to give birth. I feel like an odd ball because I don't have that natural desire to become pregnant. I have a desire to be a mother but not for a really long time. I want to adopt my babies. I can't wait to do that actually, just knowing that some day someone will give me a baby that I can take home and raise as my own. I can't wait for that baby.  Does this make me selfish or a bad person that I absolutely do not want to go through pregnancy and have a biological child? I grew up in a household of adopted kids, my mom adopted because she couldn't have anymore biologically. I don't see a difference between my adopted siblings and my blood siblings. We're all just one big family which is probably why I feel the way I do about adoption. I am dead set on the feeling of never wanting to be pregnant. When I tell people that they look at me funny like you don't want YOUR OWN baby? Yes I want my OWN baby??? I just don't want to give birth to the child. It does not matter to me if he or she is my blood or even looks like me. Come on you're talking to someone with black adopted siblings and you think I care if my children resemble me??
