So if some man said they felt as if they were really a woman, oh ... I have no way of possibly relating to that.
Okay, let's break this down, and I'll try to explain.
So if some man said they felt as if they were really a woman ... Stop, the person you have just described isn't a "man," despite their birth genitalia. By your description, this is a person with the gender identity of a female, their brain contains a female consciousness.
... but they don't want a relationship with a man ... Stop, okay the fore mentioned female doesn't sexually desire a male. The person you're describing is therefor sexually a lesbian, or possibly celibate.
It's as alien to me as saying that you feel like you're a square, but a square that has no corners. to which I raise my hand and say "wouldn't that make you a circle?" and you say "nope, just a cornerless square in a circle's body.
Try this, there is a man from sub-Sahara Africa who is black, but he has a medical condition, he is a albino. You RB Kandy raise your hand and say "wouldn't that make you white?" and he says "nope, just a black man in a white body."
if you tell me you are a woman in a man's body, I am just going to presume you're gay.
That would be transgenderism, which is gay. But knowing only that someone is transgender tells you nothing about their sexuality. Hetero, homo, bi, nothing, everything.
I consider transgender to be an aspect of homosexuality
No, it is a aspect of gay. The word gay doesn't just refer to homosexual.
I don't believe in the existence of a transgender person, transsexual yes, but not transgender.
The two terms are not the same. Transgender includes transsexuals, transvestites, crossdressers, drag queens, androgynes and genderqueers (gender-benders). Transsexual is specific to individuals with gender dysphoria who seek surgical alteration of their body to more closely conform to their gender identity, this may include sex reassignment surgery.
All transsexuals are transgender, but not all transgenders are transsexual.
For a man to feel like a woman, yet not want sex with men, basically means he's just a soft effeminate male, or a sissy as they used to be called
Sissy as a slang term is still used, and it's meaning can be hard to peg down. The term can refer to a crossdresser, which is a kind of transgender. But the term sissy can also (and separately) refer to a man who is submissive in bed, these people are more commonly call "a bottom."
And some males are in fact "effeminate," which isn't quite the same as being a sissy, having more to do with personal mannerisms. Just being who you are.
Like wise a woman who feels like a boy, yet does not want a relationship with a girl, isn't transgender either; she's a tom boy.
She is a transgender.
The key phrase is "who feels like a boy." As opposed to "knows she a woman" but likes doing traditional boy things.
Again, you're a sissy or a tomboy, but your not transgender,
A women who dresses in male clothing in order to deliberately present herself as a boy or man, would be a crossdresser, and would therefor be transgender.
and if you feel like [you are] a woman in a man's body and you want sex with men, than you're not transgender either, you're a homosexual, who happens to be very effeminate.
That is a very clear example of a transgender, and a individual who is heterosexual. And they wouldn't be effeminate, but feminine.
The key phrase is "you feel like [snip] a woman."
Here you are correct.
... are their enough gays in the audience to justify two men kissing?
Are there enough Star Trek homophobies out there to justify two men kissing, and then engaging in a steamy incredible sex scene?
Hee hee hee.
