Okay, just went through and read your account (some of it).

You are in your early teens, most adult sites will ask for your age. You're required to be an adult to access/use their pages. There are legal reasons for this.

Even sites like Amazon restrict what can be viewed by anyone under 18.

Your credit card statements will likely go to your parent(s), after all, someone has to pay the bill.

That being said, as awkward as it would be, I would recommend you talk to your parent(s) or another trusted adult about this.

You can also write them, or text them, or even email them if that makes it easier.

I would also suggest you bring up getting an LGBT+ sex education through your provider or another LGBT+ friendly source other wise you could end up hurting yourself.
