One day Padre Pio said that curiosity was a very bad thing. That left me puzzled

Only later, as I found myself tempted in very similar situations (ok, I admit it, worse situations

) I realized that a significant number of falls could be attributed not even to lust itself, but to the darn curiosity! Sometimes even - and yep, that is pride - the curiosity to see just how much I could resist temptation, forgetting that in matters of lust we are like paper brought next to fire, and that’s the only temptation we should not expose ourselves to because there is almost a 100% certainty that we will fall.
Then again, temptation does not equal
mortal sin. There must be full knowledge and deliberate consent (beyond grave matter). Did I intend to sin by looking at the image? Once I realized it was sinful, did I resist it or did I deliberately chose to indulge in the inordinate pleasure?
I once read a book by a Catholic priest describing an exorcism and there were some questionable transcriptions of what was spoken that would elicit lust…which is why the adversary spoke them in first place…I did not consider that I should confess any feeling I had while reading it, because I was not seeking lust, but rather I was reading about what a priest had to confront, and I did grow extremely humble after that reading (realizing that if I was responding in such way to those filthy words, I’d have been in
very big trouble if I had been in the priests’ shoes

), but I do not recommend it to anybody and I’d rather not have read it

But I don’t think I sinned mortally if I felt anything lustful during the reading: sexual response is a most natural thing, and if the intention is not towards inordinate enjoyment of that pleasure, there should be no sin…we should not be called to fight what is natural, but to fight what is unnatural and unordered
While only a confessor can discern if something was or not a mortal sin, I personally do not think so. You were shocked by your friend having what appeared to be an obscene avatar and, despite the reaction of your body (a most natural reaction) you still wanted to figure it out

Now, was it prudent? No!!

Lust = fire. Must be humble and turn my eyes (including the eyes of my mind) immediately away, not just towards a blank void: towards the Blessed Virgin, who is purity and chastity incarnate
