Would anyone please help me with the following in bold?

1. Winfrey was not immune from such criticisms, having aired shows with racy topics such as cross dressing, three-some relationships, and man hunting.

Does "three-some relationship" mean a love affair among three men and women? And in "man hunting," does "man" in the context refer to a male or a criminal?

2. Some of the organizations that have been recipients of funds from the Angel Network include Habitat for Humanity, Hurricane katrina and Rita: Relief & Recovery, B.I.K.E., and the Children's Health Fund.

I couldn't find any information about this. Do you happen to know about the organization?

Thank you.
