You're a man. You have a past. You masturbate. You watch porn. She does know all this y'know. I'd suggest as long as you keep all this stuff discreetly in the background she won't give a toss. Keep your photos in a remote corner of your PC and don't worry about it.
One thing, to avoid them popping up in slide shows, automatic screensavers or sharing to other programmes I would suggest not keeping them in the generic/default Photos or Pictures folder......... Mine are buried deep in My Document under a few dreary sounding legitimate folders called bills, letter, guarantees etc etc.
Now maybe someone could do a deep dive into my PC and find them? Well, if they're prepared to do that they are already deeply suspicious of me and our relationship would be fucked by this stage anyway.
