Actually, I wouldn't put it past Issei to have pure thoughts. All it would take is the right circumstances or motivation. That is to say, given the level of focus he has demonstrated in combat, he has the capacity to maintain focus and a level of clarity with his thoughts. Granted there is a clear difference between making an enemy scream in agony and making a girl scream in esctasy. However the biggest difference that I can see is where the situation takes place.

As for Issei, I have confidence in him. Why you might ask? It's relatively simple if you look at it like this. Irina wants to.... have a full-fledged relationship with Issei with the biggest obstacile being her very status as a "pure" angel. As such she began to research a way to develop her relationship without comprimising her position. Issei cares for Irina as much as the rest of his harem and friends. As such, if they need help and he can do it, he puts forth as much effort as he can. This, combined with the knowledge of what would happen to Irina should they fail fail the - for lack of a more subtle term - "intercourse" ritual, could very well help Issei maintain his focus on thinking pure thoughts. Or at least, maintain his focus long enough to make the ritual a success and Irina, moved to tears of happiness for her labor bearing fruit.
