My son was born without testicles 16 years ago we feel so alone Is there any support group that we can go to?

I'm sorry to hear about your situation; it can indeed feel isolating. There are support groups and organizations focused on conditions like yours, such as the Androgen Insensitivity Syndrome Support Group or the Intersex Society of North America. Additionally, online forums and social media groups can provide a sense of community and connection with others who have similar experiences. It might also be beneficial to reach out to a healthcare provider who can guide you to local resources.
