It happens for men as well tho, the ammount of "dilfs" and "daddy" comments on male celebrities like Brad Pitt or Chris Hemsworth, by women and guys is huge, I think it depends on the tone people use it, but yeah I totally get how this could sound offensive for someone, specially the ladies on here, sorry about that, it was definetly not in a offensive way, he as many others I've seen on facebook or twitter commenting the same thing, meant she was looking really stunning and sexy for her age, the "adjective" wasn't the right choice, sorry again for that
Anyway, I've seen many sites reporting about Ayu's performance and all of them are very positive, even Arama! did a nice and polite report, felt weird but nice at the same time lol
