Let me play the devil's advocate and ask.... what about the "sperm donor"? While you might be ok with being a single mum does this donor want to be a father? What I mean by that is how would you like someone turning up on your doorstep in 18 years time saying "Hey, I'm your child". Or, on the other hand, how would you handle having a child who has some inherited condition from your "sperm donors" side of the family and the child needs their blood for a transfusion or something???? Do you really know what you are messing with?

Nic, I think you are only considering your wants and desires. While you can do whatever you want with your life please be careful messing with other people's. A man does have a responsibility in having sex but trapping someone is a little cruel if you ask me.
