Gay activists wed in Cuba

You may know the story, but Wendy Iriepa and Ignacio Estrada have recently gained international reputation because of their marriage (see here, here, here, and here)

I have a point here. It is argued that a gay man gets sexual gratification only with a penis, otherwise he would not be categorised as gay; he would be bisexual or someone else.  Since Wendy underwent a sex change surgery, she doesn’t have a penis.  So how can Ignacio, as a gay man, be sexually satisfied with this marriage?

I think they may be confused about their sexual orientation; therefore, they have puzzled the international audience too. The media industry itself is already bemused since they are struggling on whether to address Wendy as transsexual or transgender.
