i have a 14 year old son named joseph. i recently caught my son masturbating to porn on the internet. i opened the door to the computer room and he jumped then i jumped and shut the door. i had no idea how to handle it. i don't mind that much really, i'm just kind of confused. i've never had a real sex talk with him before. is it a big deal? can i let it go or should i say something to him? and what?
