A source close to Magic Johnson reported to the National Enquirer that Magic is very fearful of his son E.J.'s partying lifestyle leading to him contracting the HIV virus.  His son has recently come out and openly announced his gay sexuality, and Magic is very worried that he might party too hard, especially when it comes to drinking since he isn't 21 yet, and it could lead to some harsh consequences for him.  Magic knows first hand what it's like to live with HIV, as he was diagnosed as HIV positive back in 1991. 

According to the source:

"Magic's tried to have a con­versation with E.J. about not drinking, at least until he turns 21.  But E.J. is a headstrong young man.  NEVERTHELESS, Magic has pointed out to him that drinking leads to poor decision-making, especially when it comes to sex.

"Now that he's 'out and proud,' Magic feels that E.J. has a duty to set an example for other young gay men to act responsibly.  That means waiting until he's 21 to go out drinking - and, even then, to watch how much he consumes.  The last thing he wants is for E.J. to become HIV-positive."
