Don’t want boyfriend to know I watch porn.

So my boyfriend watches porn and has done since the age of 14, we’ve been together a few years now and I am comfortable with him (I am also ok with him watching it) haven’t got a problem with him watching it if I’m on my period, can’t be arsed or sick. I mean everyone has to get off at some point right🤷‍♀️🤷‍♀️ anyway on my data I have the adult content filter on ( I am 18) but I’ve had the phone since I was 16 so the adult content has always been on. Anyway I can’t go on any porn sites because they’re blocked. So I try finding things on YouTube, anyway my other half has a YouTube account and normally we use it on his xbox 360 (I’m not signed into his account on my phone) so I thought he won’t see what I’ve been watching anyway. Anyway last night we was on YouTube and the “suggestions” came up, and loads of shit that I’d been watching has been recommended to him🤣🤣 he didn’t ask, he ignored it but I know he seen. Anyway he’s at work today so I want to try and get on his xbox while he’s at work to sort the issue out, how can I remove suggestions from popping up to him? I’m really embarrassed and I honestly don’t want him to know. I don’t know why.

Any help would be great, I’m kinda freaking out he’s gonna see worse when he logs back in so I need to try and sort it as quickly as possible.
