My nephew is mestizo,he is 16 now,he has had countless girlfriends if thats what you call a social life

He has also smoked marijuana

Been arrested truthfully maybe 8 or 10 times

he lives in a great area,except the graffitti you normally see is his "TAG" I think your son sounds just fine,I used to be a wild kid,trust me,they are a load of heartache and pain,your boy is a home-body,absolutely nothing wrong with that,he will find his feet in his own good time,he just isnt bugoy

One day he will come home with a shy girl "Mum,this is karen or alison or julia or whatever her name is" thats when your worries should really begin

Give him time,childhood is precious,some of us didnt appreciate it,let him enjoy the innocence while it lasts

If you really want him to get out of the house find out his interests,enroll him in an evening class for something as a surprise
