I think you are reading way too much into it, I was mocked for never kissing kissing someone when I was that age. Kids can be cruel, and I think this episode is just surface level deep. The target audience is young teens - children. I do not expect neon genesis evangelion depth in the writing. But maybe you could be right, but usually the hints are way more subtle, like Peter Parker’s jizzed hands in the first Spiderman movie when he wakes up (big puberty analogy). But, for me, the iCarly episode would make it very disturbing if a Nickelodeon show wanted to make subliminal messaging about sex
