<human>: Can you give me a shortened version of the text?

We woke up this morning and immediately I was physical/sexual with her, but we dont have privacy so it didnt go anyway. 

     Within 10 minutes she is showing me a picture of a girl and asking me who is hotter(my g/f or the other girl). I did say my g/f is hotter of course, more exotic and gorgeous. I did however say the other girl kinda looked like a YouTube person and went on to say that she looks like such a boring and plain white girl. Thats all I meant, it wasnt supposed to be a compliment but apparently my fiance thinks the girl is gorgeous so shes upset with me. 

     That started her on to asking me if the girl or the youtuber is hotter. I said I dont even care, they are both boring and plain to me and I dont care about either of them. I kept telling her(my g/f) that she is beautiful and I wish she wouldnt be so insecure, but she wont believe me unless I find 1 physical flaw in the other girl, and boring/plain doesnt count, neither does me not caring a single bit about either of the other girls. I refused because I find it ridiculous that she doesnt just accept a compliment from me, OR an answer. 

     I answer one question from her and she just keeps asking more. btw, despite the name I am a guy(transgender though, mtf pre-everything).

     I just dont know how to handle it, I dont understand why I cant just not care at all about another women, like who cares what she looks like, shes not my fiance and not want Im into. But thats not enough, so what do I do?

Im 27 shes 22. Male/female relationship for 4 and a half years.
<bot>: g/f asks if a girl is hotter, I say no but she looks like another girl(who g/f likes), therefore doesnt believe me unless I point out at least 1 physical flaw in the girl.
