Thanks Gents. All very good opinions. Yeah, he is OVERLY the sensitive one of the family, a very feminine guy and overweight, never touched a ball of anykind in his life, pretty much closet gay. I have nothing against that and have a gay sister myself. I may have underlying tones that he takes the wrong way, but not so much him as it is Ang overly protecting him if ANYONE even looks at her baby the wrong way.
Just my two pennies but these words come across as negative to me. The statement that you have nothing against being gay and having a gay sister yourself reminds me of bigots who deny it by saying they have black friends. As others have noted, obviously I don't know you or your family but what you said makes me think you're disappointed in this kid and, if that's the case, I'm sure he feels it even if he can't identify it.
This child sounds like he could benefit from some counseling and/or medication. If he's sensitive and has to endure teasing about his weight or lack of masculinity, he may prefer the anonymity of the Internet and is able to pretend he's someone else, (read someone likeable) when communicating online.
