I honestly understand the confusion surrounded by this dilemma. I am in the exact same situation. Before transitioning, i identified as a lesbian for a year, and although thats a rather short period of time, it was a huge part of my life, and i found myself fully embracing the LGBT community. I watched lesbian youtubers, watched tv shows deemed 'for lesbians', i.e. The L word, The Real L Word, Lip Service, etc, and i found myself really at ease with the idea of being a lesbian.
When i came out as trans, i had a huge part of me, and still now, self doubt, because how could i really be trans if i still wanted to watch these shows? A part of me wants to be a lesbian, but hates the fact im a guy so i cant be.
Im not quite sure what the right answer is just yet, but if i ever find it? I'll make sure to tell you.
