I'm not a homosexual, but I think it's a great catchy song. To me, I feel the song expresses what we all feel. We are all experimental where some or most girls want to experiment kissing other girls, or guys wanting to experiment kissing other guys, or even girls wanting to experiment being with more than 1 guy at a time and vice versa. I don't see anything wrong with it. Like mentioned in the song "Just human nature It's not what, good girls do Not how they should behave My head gets so confused Hard to obey". For guys and girls, it's hard to obey b/c ur feelings and emotions or curiosity indulges us. It's just human nature for anyone to want to experiment whether it be things of what I mentioned earlier or even drinking or experimenting with drugs. Katy Perry is a real person and just singing about her experience and I feel there's nothing wrong with that. Much love and success to Katy Perry.
