I see it differently:I would disagree.Yes, they've used Kirk's reputation as a ladies' man as a source of humor. But that reputation is something that has been floating around fandom for decades and has been a source for humor for almost as long. Its an integral part of Kirk's public perception and persona. JJ is not exactly an "auteur" here. Other writers and producers, who are bigger fans, were involved with the film. I think their involvement drove characterization more than Abrams.
The idea of Kirk as the sex crazed alien-STD infected guy in fan jokes and webcomics, is just a bit of unflattering fan-humor that should not have been referenced in the film, any more than some base fan humor about Batman sounding constipated should be in something like The Dark Knight. When writers handle a beloved franchise, they do well when they accept it on it's own terms, conceits and all. That means accepting that Kirk is a chivalrous gentleman, but also falls for the ladies. Not reducing him to a dishonest or manipulative philanderer, as in the more cruel jokes. The way he was having one-night stands all over the place with people he barely knew seemed more like the latter.
