Theres often talk about how gay attraction is different to straight attraction. A woman will love another woman differently than a cis man would and so on.
That's mainly a result from societal norms. Norms like men holding doors open, making the first move etc. and woman doing household chores, caring for children in a family and so on.
These norms simply don't work in gay couples (you can't both hold the door open for each other) and for that the expectations are very different.
Expectations of sex are also different. In cishetero relationships the main focus is often on penetration with penis and vagina which in cis gay couples is not a thing and while it can be possible in gay couples with trans partners, there is still usually the understanding that penetration is just one way of having sex and not the only and so its less of an expectation.

This extends to ideas of male vs female gaze. The way we are raised to look at each other, the cultural norms we have and how people are represented in media etc. of course have an impact on how we feel attraction and how we view the same and other genders.

Homophobia also changes how attraction feels. If you grow up gay and cis chances are you'll have a hard time having a teenage romance because finding other queer people your age is difficult. Not to mention social stigmas and barriers and of course the fact many only realize they are gay in adulthood. Because of this struggle it can feel incredibly precious and valuable once you find a gay partner.
It feels nice to have found someone to really connect to after feeling isolated and left out.
Theres more trust and intimacy involved often when you share a part of yourself with someone when that part of you has often been shamed by others.

Many trans women talk about having always felt their attraction towards women/ girls to be more sapphic and not like cis boys felt.
I'm not sure if I relate.
I don't think my feelings towards girls were all that different from cis boy's feelings (except for the additional gender envy I felt). But then again I never related all that much to couples in media until Catra and Adora.
Well, it's not like I didn't relate or see myself in them at all. But when I saw Catra and Adora in the show She-ra and the princesses of power, that's where I knew what I wanted, even if it was still subconscious at that point since I didn't know I was trans.
Being a girls girlfriend seemed much more appealing.

However on the other side, when I found out I was bisexual, this definitely felt gay.
Like I very much felt this mlm attraction and had fantasies about such relationships.
It felt gay, queer to like boys while presenting as a boy. It was not something expected of me or wanted of me by society. It's when you love something you're not supposed to, that's when you really learn to appreciate it.
It's easy to love something everyone says you should love (if you already have those feelings anyways that is). But queer love, where you love what you shouldn't, that is where you really learn to love.
Because most likely you don't want it, you're questioning is this worth it. Why do I like them so much? Why do I value them so much?
You just tend to think more about your feelings.

Though I did feel a certain disgust at the idea of having sex with a man as a man which I thought was internalised homophobia back then, but turns out I just thought my body was disgusting and projected that onto other men.

Regardless, now that I know I'm a woman I still don't feel “straight” when I'm attracted to men. (I do however feel gay liking women).
I think that's because this norm breaking that inherently comes along in gay attraction and relationships is always present regardless of what your relationship is when your trans.
If a trans woman is with another woman then she's a male predator invading women's spaces and ruining the lesbian community but if she's dating a man then she's just some sissy fag and if she's in a t4t relationship then they're both creeps and freaks.
When I am attracted to a man its still different than a cis woman (queer or not) being attracted to men.
In the same way gay attraction is different from straight attraction, trans attraction is different from cis attraction.
The insecurities, the stigmas and the ignorance we feel in society as trans people will of course impact how we feel attraction towards others.

That's why to me, as a bisexual trans woman, any attraction I have will feel inherently queer to me.
And yes I will say I'm gay for men. People might say it's technically untrue but that implies some rigid objective definition of the word “gay” which doesn't exist.
Gay and queer have often been used interchangeably and I will continue to do so because I want to and I think it's funny on some part. But also because I can't stand it when people try to force these labels into rigid boxes as if the whole point of queerness wasn't to break out of societies preconceptions about sex and gender.
