Yes.

Gynomastia is a thing that causes some boys to endure a lot of bullying in school. Erectile dysfunction causes issues for older men. The treatment for both of those conditions is gender affirming treatment.

Loads of others, too.

But more to the point, it should not matter why a person needs gender affirming care. That should be a decision between a patient and their doctors, not me, not you, and not the government.
