Why is there so much more focus on guys kissing abilities than girls?

on the internet and in magazines it is all about how guys have been bad kissers, girls describing bad kisses and ‘how to kiss a girl‘ and ‘how no to kiss a girl’ Why is this? i assume girls are open to making the same mistakes as guys. Is it because guys lead or is it because girls analyses kisses far more than guys do and unless its exceptionally bad they ain’t taking notes? im really curious and don’t think its really fair!
