Sex
Depends on the mood. I think that it could be very sweet at times, and other times, well
it just might be sex.
Marriage Prospects
Seems that they could easily get married if they both loved eachother. Duo seems to be the
type that would ask someone to marry him.
Hints
In the show, Wufei and Duo don't really talk much, although Wufei doesn't really talk to anyone.
Duo seems to understand to leave him alone when needed. And there is always that pic
of Duo and Wufei holding hands. Friends? I think not.
Overall
I think that both Duo and Wufei could either be dominant or not, and they would go well together
in a relationship. Duo in the fanworld is so very different from Duo in the show, but they both
seem to have personalities that would click easily. Duo is the kind of person that could slowly
open up Wufei to not being a total prick at times. Duo would be the fun-loving kind of person
that could show Wufei a really good time(was that a sexual hint? maaaaybe).
