Found husbands old explicit accounts online

As the title says, I found out of my husbands old accounts (years before me). Which he’s tried his best to delete but when I do a Google search on his old user names, it shows he’s taken explicit photos of himself which he said he’s never done before. If I’m honest it’s made me quit sick to my stomach as I didn’t expect this from him and totally disappointed. I’m currently 9months pregnant and know for a fact these are way back before he met me, I also understand people have colourful lives before relationships but just don’t understand why he’s lied and said he never took d*** pics but had. 😟

*update:

So how I came across this is because an ex friend of mine who I thought was a good friend came across this around the summer time as he’s on the same site. Apparently Looked through the archives of a username and started to put doubt in my mind. He said he did it because he had feelings for me and I had to break off the friendship, but sadly since he’s done this it’s stupidly put doubt in my head, maybe because everything seems more heightened now I’m pregnant. Also doesn’t help when I first met my husband he asked me strange questions like: “have I ever cheated” or “have I ever been on ‘X,Y,Z’ sites because I wouldn’t want to date someone who had”. Ofcourse I hadn’t and maybe when I mentioned this to my friend he must of got suspicious and done his own digging as things aren’t too good in his own relationship. 🤦🏻‍♀️ I think what I’m trying to say is, I’m not keen on me getting quizzed or potentially judged on a subject that he’s clearly done himself and denied it, if someone can lie about this, makes me think what else are they hiding?
