Throwaway account since GF uses reddit.

So the other day, I was working on rebuilding my computer that I normally use, and I was using my GF's laptop to look up some info.

I wanted to go see an older post I had had made on r/buildapc regarding some questions I had about a graphics card.  So without thinking I hopped on reddit and clicked the username space without really paying attention to the name.

Then I see the post history is obviously not my account (nor is it my GF's account that I know of), and that all of the posts are regarding selling used panties.

Honestly I'm not sure what to think.  If she is doing this, I feel like while she isn't really "cheating" on me....she's still not being 100% faithful.  I feel like we both really care about eachother, I've never had any reason whatsoever to feel like she's even interested in anybody other than me in the time we've been together.

What I guess I'm asking is how do I bring up to her that I found this (and that I wasn't snooping, it was purely chance), and that I'm really uncomfortable with it?
