Melody, I'm no doctor, but I think whatever they put you on, it shouldn't nuke your libido. Lots of cis women suffer from decreased libido, and that can be caused by hormones or by other factors like anxiety, stress, undiagnosed underlying medical conditions, etc. Medicine seems to be behind on treating such issues because of overhanging Victorian notions that "proper" women don't have disgusting libidos.
It's also a myth than women don't get erections. They just aren't very noticeable to others (unless you stick your fingers down there, am I getting too explicit?).
And, like the others said, T is the sex[ual] hormone for women as well as men. You're levels should not be all the way to zero.
