I was also wondering about this, because at the moment I am studying the writings of Srila Sridhar Maharaj, and the more that divulge with Srila Govinda Maharaj's devotees, the more that I feel that Srila Govinda Maharaj is my own guru... but who knows that until I am totally ready...

Anyways, it is likely that the people who I will meet will be from ISKCON. And being attracted (romantically, not sexually) to those of the same-sex, it will be a great demand of tolerance on many peoples' sides. I do expect myself to follow no illicit sex, but at the same time, I have attachments to companionship.

But yes, marriage is considered a secular institution outside of Gaudiya philosophy. Maybe one day I will meet my Krishna conscious man, or maybe I will be led a life as a single person. Who knows? ^___^ But love Krishna within whoever you wish!
