Help!!

I am 14 years old and I have begun masturbating but I’m a really confused on several things so any information u could give me about the following would be really helpful.

1. I have done clit stimulation a lot because it’s the only thing I know how to but I have gotten bored of it and it and I want to try something new. I have tried to have a g spot orgasm but I haven’t been able to so any tips you have on that would be great

2. When i do clit stimulation I try different things out, shower head, toothbrush, finger but I need to be able to do it at night and for it to be quiet. The toothbrush was to loud and I only have a shower head in my parents bathroom. I have also gotten tired of using my fingers

3. I really want to buy a dildo but I can’t buy one so any ideas for safe substitutes

4. When I rub my clit I feel it in my legs and their shaking and then I think I climax, is this a orgasm? And what do u do after u climax, do u keep rubbing or do u stop.

Thanks!!
