I agree with everyone else. If he is open to the idea then it's worth a try. But I would be sure to let him know that he is in the driver's seat, so to speak, and that he understands it's his therapy and it's solely for his benefit. If he gets in there and doesn't have a good rapport or doesn't feel like he can open up to the therapist then let him know he can try someone else. Or, if at any time he feels therapy isn't helping him then let him know he can always stop. It's his choice. My son (now an adult) also went to therapy throughout his teens. Ultimately, after trying a couple different people, he found a young(ish) therapist that he really clicked with. He saw him off and on for several years and it was very helpful for my son as he was also in the process of coming out at the time. It was nice to know he had that outside support. But when he said he was ready to stop therapy I supported that too.
