On the 0.00000001% chance that this isn't fake and gay, and is just in fact very gay, I will share an irl similar situation with you op.
>Have younger female cousin from THAT part of the family
>As she hits college years, she comes out as lesbian
>Despite her parent's hope that it was just a phase, it continues onwards and she even gets a long term serious gf
>Time goes on, and it begins
>She comes out as trans
>She was a man inside all along and now wants to go all the way
>She changes her name and pronouns, takes the hormones etc
>Gf still loves her and wants to support her
>Ff a bit, and she has facial hair and goes in for top surgery
>Is now living as a man with his gf, and all is apparently well
>However...
>A few months back, the news spreads that they have split
>The gf said that she tried, but she's a lesbian, she doesn't feel attracted to men, and can no longer see the girl she fell in love with in him anymore
>Cousin is shattered, as she/he thought that gf was the one, and wanted to marry etc
>Last we heard, gf was with a new chick now and happily carpet munching again
>Cousin is still alone and broken up about it
Long story short, if you start a relationship with someone of a particular gender, and they then change that gender after the fact, you may have some trouble staying attracted to them afterwards. They may still feel the same way about you but your perception of them will alter.
If you love gobbling their cock now, then you will probably still love gobbling it later when the fake titties go away but you will just be gay instead of progressive.
Decide carefully, but it may just be better to make a clean break.
