Questions I have about sex-related stuff as a young trans guy

Hello! I am a -18y/o trans guy and I feel awkward asking these questions to people because I feel like I'm too young to be asking them/I am uncomfortable asking people abt my personal pleasures. So I head to the internet! :D

Q1: When I get bottom sugary, will I still be able to orgasm?
I know I wont be able to produce semen(sad) but I would like to know if I will still get that "climax" feeling and will I be able to enjoy intimate stuff with other people in the future?

Q2: Is there any way to completely hide the fact I'm trans completely?
My main goal as a trans guy is to erase all parts of my life where I was a girl, leaving that part behind forever would be my dream. I am worried though that there will be some parts that will make it obvious, especially in the bedroom. What are some ways I can possibly lie about the reason I can't produce semen or don't have a prostate?

Q3: Will I be able to enjoy anal?
I guess this is just a general question, but if I don't have a prostate how can I enjoy anal like a cis gay man? (Side note, I don't feel anything when I put something in through the "front door" so idk what's going on there)

I really hope this doesn't get taken down because I don't really have a safe space irl to ask this stuff, nor do I know anybody like me.
