You want to remain young and innocent and feminine. that's not going to last forever unless you do something about it. As it is, there are basically two ways of doing this (besides just doing nothing and eventually masculinizing)... one is going on puberty blockers, where you'll essentially delay the progression of puberty... it's generally not a very good option, especially not long term, since it is quite unhealthy. It will keep you as you are, buy you time, so to speak. The other is hormones (castration is technically an option, but total loss of sex hormones is also unhealthy). This has side effects. Your body will become more female. Your skin will become clearer, your hips will widen, you will stop becoming taller. You will become weaker, you will lose some of the general acrid male body odor, you will develop breast tissue. It will also make you infertile when you take them for a long period of time, this may or may not be reversible (if you are worried about this, bank sperm). You will stop growing much taller, you might experience emotional changes, your body hair will reduce and lighten, with the potential exception of any already on your face. Essentially you will start looking a lot more feminine, and this is the only way for you to do this. You don't necessarily need to change how you dress, your name, or anything else if you don't want to. It's up to you.
But yeah, talk it through. don't actually do this unless you want to... just be aware that "Just wait it out, it'll go away" is bad advice... we like to meme that everyone would be better as a girl, but it's not entirely true... it's a personal choice, and you sort of have to make it yourself... tbh, the only reason we're actually continuing on about this is that you remind a lot of us of how we once were and you're still young enough to not have the regrets we have, while having your options open and available. You're not exactly the same, but you are similar.
