This comes more from Japanese culture and a bad translation.
Like, Goku doesn't say he never kissed Chi-Chi or that he doesn't know what a kiss is, the joke is that Goku is old fashioned as old culture dictated that kisses were something private that couples shouldn't do in front of others, and is shocked at the audacity of Trunks and Mai asking if you can kiss in front of others and that he never kissed his wife in front of others...but Vegeta misunderstands because Goku only implies the latter.
It's why in Japan no one cared or made memes out of it, Japanese fans were just like "Goku was raised as a hermit by old men and his wife seems old fashioned herself...yeah, this makes sense" because...well, fans around the world are usually the samein many ways and will heavily criticize bad moments or scenes, the kiss joke scene wasn't one of those there.
I think the issue was that the joke was too much revolving around Japanese culture and less blatant than it should be for people around the world.
It makes the joke go from Goku being old fashioned and Vegeta misunderstanding, possibly also playing with the fact that Vegeta is kinda a foreigner himself, that Goku somehow never kissed his wife or knows what a kiss is, into everyone thinking the same as Vegeta and putting it as a dumb joke that makes Goku into a bigger idiot than ever.
I mean, kisses were so private that many traditional weddings or Shinto weddings didn't even have the couple kissing because why would you show that in front of others!?
To be fair, i don't know how to translate the joke without explaining so much it stops being funny, it just ended up being an unfortunate gag that made many people think Goku doesn't know what a kiss is despite knowing what it was before when talking to Old Kai.
