How can I find my sperm donor (biological father)?

this is true love, I hate to sound mean but you cannot go out there and find your sperm donor, He didn't want a child. He was just helping them people out who couldn't get pregnant properly. If it was the case of people finding there sperm donor then he would have loads of kids going to him, I would talk to your mum if i was you. Its very serious, Don't go and look for him hunnie, Its not for the best!.. Good luck xx
