Trying to teach adopted 10yr. old about his junk..

He's 10, about to be 11, and has no idea about his penis or the feelings he gets from it. So I sit on his bed and try to have a serious conversation with him on how a males penis sometimes gets bigger... When all a sudden he starts sobbing and then crying hystericallyNow a little bit of a back story: his Bio-father finally came into his life when he was 6yrz old, and according to his mom, he cried and hates his Bio-father whenever he had to go see him on the weekends because of what appears to be abuse. Now, ive only been in their life for a couple years but have already adopted the kid as my own, after his Bio-father relinquished all rights to him to me. I feel the child was abused because of tidbits he would tell my wife and I, but honestly he literally breaks down crying if we even mention his Bio-father so we can't get much out of him.Well tonight I caught him tugging on his little guy so I figured it is time to explain to him about the certain feelings that we men get when playing with it and what they mean. Well when I sat him on the bed, 30min after I caught him, and started to explain he bursts out crying like he is 2 yrz old and literally goes into a panic attack...So it basically sounds like he needs a therapist, am I right? Like maybe there is some abuse he is hiding he won't tell us? via /r/Parenting http://ift.tt/2uIXdBN
