Girls and Porn

Ok this is what I dont get.... Why if I, a female, enjoy looking at porn and getting off, is it wrong to say??? I mean guys are not the only ones that masturbate....girls do it too. Hell there are a lot of girls that can not get off on penatration and need to "handel" it themselves. So my question is why do women have to keep it hush hush when guys can talk about it any time?????
