Difference between mani and mazi

Q: For a long time now I have found it difficult to distinguish between the features of mazi and mani. I noticed that my everyday discharge has a smell to it, like the smell of mani. So when I do get mazi I feel it could be mani, but I'm always unsure. This is because it looks thin and white on my clothes, but after wiping, its majority white but looks a little yellow toward the end. The discharge is mostly thin and white, but the last part looks a little yellow.

1. Is ghusl fardh upon me every time I see the discharge look like this?

2. Every time I see, what looks like mazi to me, always has the same smell as mani, but so does my everyday discharge. I'm kind of confused? 

Can a girl become baaligh at the age of 8?

Q:

1. Was I baligh at the age of 8? Since I was 8, everytime I got in the shower I would throw water pressure “down there” until my body shook and was satisfied (I believe this was an orgasm, and I may have emitted maniy but I really don't recall). I read that mani is supposed to be thin and yellow, but I have only ever secreted white or clear discharge, so it was most likely mazi. After that, I would take my full shower without the intention of ghusl. I only started praying and fasting regularly at the age of 11, when I got my first period. Now, 18, I just learned that a woman is deemed to have reached puberty when one of four things happens:

1 – When she reaches the age of fifteen.

2 – When her pubic hair grows.

3 – When she emits mani (fluid released at climax).

4 – When she starts to menstruate.

Second Question: Does this mean I was baligh at the age of 8? Do I have to make up for 3 years of prayers and fasts that I did not do before the age of 11?  I continued this habit in my teen years, after my period at the age of 11 when I was surely baligh.

Third Question: My parents never had "the talk" with me and I did not know until recently what masturbation is, the fact that it is haraam, and that ghusl was mandatory after that. So I would perform the habit then take my full shower without the intention of ghusl. Does this mean I have been praying in the state of janaabat and have to make up for 7 years of prayers and fasts?
