It feels like this perk should have been opened a long time ago. Asuna's behavior looks like she has already passed the stage of "love" and keeps Kirito by her side simply because she is used to him.
Well, it will open when Asuna starts actively having sex with Inoda in irl.
By the way, Inoda's blog is made as the story unfolds, not in advance. As are the messages on the phone. And about Asuna's comments below and her opinion about Kirito and Inoda. I haven't found it yet.
And here is the next development of the "Sperm Eater" perk.
By the way, this perk is a reference to the event of Inoda and Kyoko in the hotel where she explained to him that pills are very harmful to health if you take them often.
Oh, and there's not a single mention of Suguha in the parks, so the cult should be happy

. And those who were hoping that she would also fall on Inoda's dick should be sad. Of course, this doesn't give a 100% guarantee that she won't become someone's toy again, but it does mean that she will have a separate storyline from Inoda.
And here is the continuation of the development of the previous perk.
The final stage of the perk.
And here is the perk after "Strict Contraception". Quite a late perk, although far from final, there are still 3 developments to come.
The next stage of perk development.
The next stage of perk development.
And the final stage of perk development.
