Of course it's normal its because of her hormones, Ever guy or girl has at least watch or thought about watching porn more than once in there life time. Even I have watched porn. It's very easy to be addicted to porn and very hard to stop watching because of the way it makes you feel well watching it.
My friend (who is a girl) thinks she is addicted to porn. She is really worried about it and has even watched it on my laptop a couple of times, but she won't tell anyone else. Is this normal for teenage girls?
Its definantly normal. You shouldn't be worried unless she's extremely worried. But it's normal. And make sure she knows thats its not weird or creepy, because a lot of people watch it. It's because of her hormones, and she probably can't stop because of the way it makes her feel. So don't worry:)
Well watching a little every once in a while is normal but watching to much is not very normal. Tell her to think of other things and try to occupied herself with other things. Hoped I helped! :)
