Please remove the photos of your daughter from your sperm donor profiles across the internet. If you want to post photos of yourself, no one can stop you, but can you imagine finding out your dad used photos of you as a little girl to try to get more women to let him impregnate them? Have you told her about all her half-siblings yet? The longer you wait, the harder it will be on her when she finds out. And with DNA testing as popular as it is, there is no way she won't find out. No matter how "discreet" you think you are being, at least one of your children is bound to figure out who you are and get in touch with her.
