K my 17 year old son never opens up to me. Hes not introvert he loves being with groups of friends and hates being by himself. Hes not gay he constantly talks about this girl named gabby to his ...
Sometimes teenagers can be weird like that. You need to try talking to him. Spend more time with him whenever possible and see if you can get him to open up. Tell him you love him and you'd love to hear about what's going on in his life. If you are open with him, maybe he'll start opening up a bit.
Good luck,
