You ARE a normal teenager. Everything you wrote is, for lack of a better word, normal. You are experiencing the effects of hormones during the first part of puberty.
You're going to have mood swings, 'weird' thoughts, all that. It's all natural and every boy goes through it to some extent. Boys your age will talk a lot about sex, girls, etc. Most of that is just wishful thinking or outright lies.
They learned the words and are repeating them. Kind of like the old saying 'monkey see, monkey do.' You're in fine shape, buddy. In fact, I would say your much better than that.
You're taking the time to think about what's happening. All I can really offer is that you'll get through it all. You'll find out who you're seriously attracted to (girls, I'll bet money on).
But, if it's both, or just guys, that's fine too. Again, you're just going through a bit of 'hormonal imbalance' right now. Give it time.
You'll be fine.
You are making way too much of this, you said it your self you can never see your self with another guy. That statement is your true feelings. What most kids your age go through is the first time they have to be at school in the showers after gym, seeing all those naked guys makes any kid wonder if he is gay.
Thats normal so don't worry, you know the answer an the answer is no you are not gay. So put this aside forget it an just be a kid.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
