While I agree that pornography can be addictive to some, I cannot imagine your ED was caused by a few photos, as myself, like many here, have probably seen more than would be cared to admit and suffer no consequences (yet?). If you are indeed from Israel as your profile states, perhaps sexualisation of things is more censored in everyday life, so a slap of hardcore porn might be draining and unexpected for you. For more regular folk in Europe, UK, the Americas etc, sexualisation is everywhere from general magazines, to high street shops and music videos and so hardcore porn would have less of an impact.
I’d also like to point out that a decrease in EQ does not always equate to ED.
Nonetheless, your care seems genuine so thanks for the heads-up, at the very least some may view less porn which cant be a bad thing!
All the best! :)
