A question to the ladies. I am 18 years old and I have a sister 4 years younger than me. Do you think it is normal to masturbate so often? It's the 5th time I've caught her doing it and since I'm a super loyal person I pretend I haven't seen anything. Because we sleep in one room, on different beds it happens to me even at night to spot her. It worries me that her friends are influenced by these things, and they are, to put it mildly, sludge. My sister and I are polite and responsible, but I'm afraid she's in a bad company and goes out with guys who can take advantage of her in some way. Now everyone has phones and has access to everything and it is much easier to get to know this and that. When I tell her which things are harmful and that she should not deal with sludge, she is angry with me for days as if I were a villain. And now I don't know where he learned to do it by masturbating. In the history of my laptop, I find a search for porn and over 20-30 links. I don't know what's going on and I'm wondering if I should talk to anyone about it.
