I can offer these observations.
Firstly, I don't quite see why I should pretend to anyone. I walk into a shop and ask for a packet of cigarettes, (as you do), I don't start by telling people them my life story. I've been a member of a computer forum for many years. I've made a number of references to my wife and nieces. I don't actually recall ever telling anyone that I'm transgender, a gay gmale, married to a woman, (

), or even that I'm gmale. If they choose to assume something about me, that's up to them, frankly.
I've also played a lot of computer games. I invariably play a female character as I feel more comfortable. I just don't get into that discussion. Again, if people want to assume things, that's up to them. I'm currently an elf female, very old, I tolerate you humans for now.
I have never chosen to meet someone, but if I did, I would be who I am. I'd do my best to answer questions, that aren't rude. 'Have you had your op yet?' Have you cleaned your d**k/pu**y after the sex you just had?'
The thing is, how do you feel about being trangender?
If you're still uncomfortable then that's the problem, not the reactions of others. It's my experience that we create our own reality. People treat us how we want to be treated.
Oh, you're female, I thought you were male!
Oh thank you. I am actually male. But nice of you to say I look female.
But you have boobs.
Yep, but much like my acne I hope to deal with that as soon as possible.
Get the idea?
Now, if the response is something like, 'Well I wouldn't do that and I wouldn't go with someone who did.
I understand and I'm sure your views are intelligently held, but I don't remember asking you.
How do you feel about that?
