I (25M) found old social media videos of my gf (25F) “babecocked” by bbc on porn sites. Not sure what the next move should be …

My gf used to sexualize herself on TikTok. She doesn’t anymore, she’s stopped for at least a few years. However, out of curiosity I decided to just do some google searches of her TikTok username. It took me about 5 seconds to stumble upon her old videos being posted on porn sites and jerked off to side by side in the videos. She’s on at least 5 different websites that I found, and they have a pretty substantial amount of views.

Not sure what my next move should be? Maybe tell her? Or keep it to myself? At this point now that she’s past that point of sexualizing herself I feel like it would probably upset her to find out. But just leaving things alone feels odd to me
