>>18112528 (OP)Depends on what was happening and like
>>18112940 said, what specific kind of porn it was. e.g had fetish?, male/male?
If you were merely staring at it, the situation is somewhat recoverable, if you decide to bring it up, you were shocked at what the image was and couldnt look away. If you were masturbating while she walked in, nonono soi: take it to your grave
(unless you can think of a REALLY good idea)
I would also try easypeasymethod.org if you struggle with not looking at porn, shouldn't be hard to stop with it
