I cannot tell you if it is male or female from those pics plus
I don't believe it has sexed yet. If you top it will become bushy
two dominate branches will grow out from the level you top.
You can also train a plant to grow about any direction you want
it to. I have seen plants tied to the ground and grow along the
surface of the soil. Tying branches to grow where you want
them to is an option. Id say you do not want it to grow so
tall that it is at the top of the fence right?
I say leave the plant alone it already looks happy where it
is. An environment change could also stress the plant.
