Basically Starkster and Frankie beat me to postage. I looked at your profile and you are only 13 years old. Now the thing about being 13 is that you are obviously very young (Nothing wrong with that at all) the thing your mum will be worried about is that being on the internet...everyone is watching.
Let's say you record a bunch of hate videos towards an ethnic group. The internet in all its uber power may then copy that video and spread it around. You then go for a job but then they find out that you spoke prejudice against people on the net. The company doesn't want someone like that representing them and so you are forever shamed from that potential employer.
Now you say you sometimes make sex jokes and are bitchy. Again you are only 13 years old and stuff like that is looked down upon by parents, a lot of Youtubers and people in general. That doesn't mean you have to be a stereotypical girly girl and not be yourself but you just need to think about how you want people to see you.
There is nothing bad about being yourself and not saying rude things. Humour can be created and said in many forms of speech and still be very successful without having to cuss. EXAMPLE! Your indie video begins with you being very informative about the game you were playing. Why not do that in all your videos? Even though you are 13 you have a voice that really supports that kind of commentary.
In a way I think you have the potential to pull off really informative indie game reviews. Why not make Indie Monday about reviewing various indie games that aren't getting much spotlight? Not only will these developers see that you have put in the time to look at their game but you will then potentially build connections, improve your commentary abilities and be seen as something who can be taken seriously on Youtube.
Even though Youtubers like that PewdiePie fellow swear and say offensive jokes doesn't mean that is the key to success. In a way he has probably locked himself out of a lot of potential career opportunities if his channel ever went south because a lot of places don't want to support commentary of that caliber. I for instance like to replace swearing with no serious words. EXAMPLE! 'F**k' turns to 'Fudge'. Simple, respectful and it sounds funny when it rolls off your tongue during commentary.
As I said, step back and think about how you want to be seen. You don't need to swear to be yourself and if you really took your commentary in a professional direction like you did at certain points in your Indie Monday video then you have the potential to go a certain direction and become successful from it at such a young age. Just got to put those brain meats to work.
I wish you the best of luck
