Is this cheating? Should I tell him? Read whole thing pls

Partner and I have been dating a little less than 2 years or so now. while back I was lonely lol and wanted to make friends. I have no social media and I’m horrible at first hand talking and socializing. Have anxiety due to past friendships. So I downloaded a dating app which you can also have like a friend section on there. That’s why I downloaded it. I downloaded a few different ones to check out... and when I did, there was this “FaceTime with strangers” app. And I downloaded that cause I thought it could be a good way. But little did I know, there were literally all guys when I swiped and some had dicks out. Obviously I swiped past it and wasn’t my intention to see those. This was a while back and throughout my entire relationship my boyfriend has prioritized the honesty policy. But this type of honesty is more like a I’m raw to the inner core, if I have a thought that I keep to myself I almost feel guilty. (Pure thought not bad ones) So believe me when I say that this has been eating at me for like a year now. I downloaded the apps about a year ago, maybe half a year? (I guess it’s pathetic but I’ve been through a lot and I’ve met my old best friends online) but anyway... I guess what I’m trying to get at is, should i tell him, I feel like it’ll look bad. 1. I downloaded random FaceTime apps, and dating ones

But that’s only cause I couldn’t find any other friend making apps. And social media isn’t mine and my bfs thing in any way. But I feel like that by itself looks bad. I feel like he wouldn’t believe me if I told him it was for friends purposes. Him and I have really been keen on the “we are each others bff’s” type deal. But secretly I kinda have a desire to have other actual friends again. I mean duh, naturally I need some girl time. But anyway, please don’t think this is stupid or a joke or embarrassing of me. I just really have been feeling guilty because of the things I’ve run across. 1. I don’t wanna tell him because I know he’d be upset and probably think that he needs to leave me over this because the whole agenda of these dating apps from outside look is hard to believe I guess (his point of view I’m guessing) and also because duh, I saw dicks on accident! My bf and I were already moved in together at this time so I feel like maybe if we weren’t moved in, and playing hubby and wife roles, that it’d be more acceptable. But anyway I’m rambling and I feel like no one will read and take time to analyze this for me. I just need help. I don’t wanna tell him AT ALL because I wanna avoid the situation. I feel like I’m not lying by keeping this from him. I’m just kinda embarrassed of this. Also I feel like in a relationship you don’t have to be so raw and exposed to your partner. A little privacy isn’t bad. But he’s definitely established a different way of going about things that I’ve sort of fallen into the groove of. Please comment some insight and help me on what you guys think is best. On this situation. (I haven’t downloaded any in like over half a year)
