Is Ricky Martin Gay?

The reason I ask is that he just had twin boys via a surrogate mother. When it was announced that Caly Aiken did that it was "PROOF" he was gay. Okay, he and a female friend each wanted a baby so he donated his sperm and she donated the egg and temporary housing.

Either way, both singers became fathers without being sexually involved with the women giving birth. So I was wondering if Martin was gay or if two different standards were being applied.
