This was a much harder question than I thought at first...
I'm female...and would absolutely support/nurture/assist my boyfriend in being all that he/she could be...

But at one point, I have to also choose for myself whether I want to be in a relationship with a woman. I don't know if I'd be as attracted or change myself that much. I know I would still love my friend with some strong love, but whether I wanted to continue in a sexual relationship would take a lot of time and self-analysis. I support the boyfriend completely in his decision, but then she would have to also support me in my decision for what is best for me.

It depends on the person, the relationship, the timing, the age, how they change during the process...
lots of variables for such a simple yes/no question.
