Ok 2 things to start, I am scrupulous and I am a man who has same sex attraction(those two things will make this a lot easier) I was reading a nonfiction book about early america(specifically massachusetts) and the puritans and it explained how they would punish criminals, it talked about one case where they stripped a man and whipped him. I naturally have a tendency to find that sexually exciting, and as I started to read that part(it was only 3 or 4 sentences long) I realized this material has potential to arouse me, but I thought I would plow through anyway and read it since deep down I was thinking that it's a non fiction book and its explaining history-not a porno so I should be able to read it even if I find it arousing(and by the way I was just reading it, not fantisizing or falling into lustful daydreams). So I read it anyway, of course all this happened in maybe 10-15 seconds.
Now I am being very scrupulous about it and part of me thinks I comitted a mortal sin since I deliberately read on even though I knew the subject matter had potential to arouse me. But the other part of me says that I never had any intent of picking up this book and finding anything sexually stimulating in it and I continued to read on since it is of historical importance. And even if I did deliberately read it it was only briefly(around 10 seconds) and I have an examination on conscience that lists "brief entertainment of impure thoughts" as a venial sin
Do you think it was mortal?
