I have a problem with my brother. I know that he just hit puberty and he is always having a hardon around me. I notice it but just ignores it. But the other night I went into to his room and I can tell that he was masterbating. His face was shocked. But the thing is that he had a picture of me. I pretended that I didn't see anything and left. We live with our mom and she is always at work. I'm 17 and knows somethings about sex. What should I do?

This is too important to not talk to your mom about. It might be hard, but you have to tell her you have to talk to her about something very serious. If it is easier - print off this and put it in an envelope and give it to her to read at work.

You as his big sister are so far doing exactly the right thing. Keep on pretending you don't see his hard-ons and know he is masturbating. But know that you do know it - let him have privacy and always knock on his door.

Your mom needs to have a discussion with your brother. It is not so unusual for a brother to use a photo of his sister to masturbate to - because that is a picture he has. He may well be confusing the love he has for you as a sister with sexual feelings - that too is normal. Normal means it happens a lot - it does not mean it is not something that your mom doesn't need to be concerned about and help him with.

If he needs a picture - and most guys do - your mom needs to help him find something more appropriate. And then she needs to talk to him and figure out whether something more is going on. It could be nothing to worry about at all. Or it could be soemthing he needs counseling for.

This could also be a time where your mom needs to find a man she can trust to help him with his growing into a man issues. A mom can help, but there are some things guys just need to talk to other guys about.

Did you talk to your mom?

All teen age boys are like that, always carrying around a HARD-ON. So just ignore it and help him avoid being embarresed, As far as him looking at your pic and getting off on it, It probly is because he has nothing else to get off on. Why dont you leave an advertizing flyer that shows woman in there undies, like a Victoria Secret booklit. Then he will have no reason to use your picture, plus should get more enjoyment when he pleasures him self.

I don't understand how any siblings can have a sexual enticement to one another, it's sickening. I'm not being a jackass, but how is that even possible. It's common sense that brother's and sister's do NOT think that way, no matter how horny he/she may be. The thought jst should not ocme to mind, I don't care how old, or who, what hit puberty. No excuse in my book. I would make sure my brother knew that I know what he is doing and embarrass the living soul out of him. That's just uncomfortable and disturbing how one can even be aroused by his/her own sibling.

People have no control over what they find arousing - they only have control over what they do with their arousal. The brother in this case needs to learn not to use his sisters picture because of what it does to him. He doesn't need to be embarrassed - he just need a more appropriate outlet for his feelings.

I agree 100% with big John's comment.
Even If I find my own preteen son masturbating to my older daughter's picture I would do the same... no big deal.

embarassment will only confuse central issues. When I was just 8 or so I walked in on my 27 year old sister drying off from a bath. The image is still burned in my brain. I would not have been so if my emotionally abusive
brother in law had not brought it up every time I looked at a girl for the next 35 years. I am not sayin sweep it under the mat, but deal with it without added emotion. post does not give much else to work with. I would add that this erection thing is just a phase, will go away when he's 70 or so.
