Do I tell my mom that I'm masturbating?

No, absolutely no reason to tell your mom that you're masturbating. If it seems medically relevant, then you could tell your doctor if you like.

You masturbating is your personal, private business... I wouldn't tell her because of her reaction being good or bad either way...

no, masturbating is a normal stage that most people go through in their lives don't worry about it, things like that should be kept private.

no there is no need as it does not effect anything medically and really as to telling your mom that is up to you and i would go by how much you think she will freak out as to weather or not i would say anything

Yes, I'm sure she would appreciate that conversation. Make sure you tell her exactly how you do it. But seriously, I don't think it's necessary.

Dude, your mom and the doctor don't wanna know if you're wackin' it...

I'd love to hear how that conversation would start.

No, please spare her. She'll never look at you the same way again.... This is normal i suppose, but NOT something anybody but you need to be aware of...

No, it's not her business and she has no reason to know. She would probably rather not know anyways

Why your mom? Not your dad?
