<human>: Hi guys I'm fairly new to reddit so sorry in advance if I mess this up.

I'm an almost 21 year old female and I'm (unfortunately) still living with my parents as I'm medically unable to work at the moment. I live with my mum, dad and 19 year old brother who is moving out to go to uni in October. 

I just found out today that my father has added a parental block to the internet. How did I find this out? Because it blocks tumblr blogs that are marked 18+ even if though I know there's no porn on the blog I was trying to access (or at least none that I'm aware of, I was literally just trying to read a text post). 

I'm really upset about this because I frequently feel like my parents treat me like a child even though I'm obviously not. For example they only told me the parental control pin code for the tv a few weeks ago (I couldn't even watch Scandal without asking for them to enter the pin and that's not even 18+). And it's none of their business if I watched porn anyway, right? It's like one step forward and two steps back. 

I'm also a bit paranoid now because I've been looking at.... personal items for myself the past few days (on incognito tabs mostly but sometimes I forgot, but I deleted my history afterwards. And it's my own pc) and now I feel like he knows or something?? Is that even possible? The timing is kind of freaking me out here. And of course I can't get on the website I was looking at anymore. 

My parents are pretty chill generally, so I don't know why they're doing this. They're fine with my brother and his girlfriend staying in a hotel together but not this? I don't understand? Any advice on how to start a conversation with them about this would be really appreciated. I have horrible social anxiety and I'm not looking forward to this at all.

Can you condense the text into three sentences or less?
<bot>: I'm a legal adult living with my parents and they have just added a parental block to the internet. I don't know how to ask them to remove it without any awkward conversations about my internet habits.
