Exactly it's your choice if you feel that big a need to transition then do so as you only be miserable if you don't. I'm lucky to have a soulmate that is female to male trans man and he understands my need for breasts as he feels I maybe slightly intersex myself with my physical attributes. Plus I have met trans women with and without there original penis and they still as female as any cis female out there. 

You have to do whatever makes you happy and your partner will have to adapt herself to fact to yeah she will technically be in a lesbian relationship but you still love her with the same ferocity as you always have. Good luck Billie
