Is it normal that i want to be a surrogate mother?

I want to be a surrogate mother for friends/family only. I don't need payment, but the friends/parents must care for me in my 9 months of pregnancy, etc cook food, household chores, take me to the hospital, massage me when I get back pain...etc. I think being able to carry and give birth a child is a wonderful thing - though I feel that I am not emotionally ready to raise a child or I have not found a good partner yet.
