PTSD arises from all kinds of sources. A transgender individual may not have PTSD at time of enlistment or even understand they have gender dysphoria at time of enlistment, but may still incur it during conflict or aggravate it during conflict. There are many combat veterans who never realized they were trans until they joined the service.

I'm not making the argument to take away Viagra from vets who need it. But Viagra in this case would be used to facilitate secondary symptoms of PTSD that include depression and anxiety, particularly if E.D. leads to problems at home. Otherwise, what is the necessity of it?

The point is, what's the debate on how we cover military medical? Bare bones basic or do we allow for mental health? If so, you can't exclude one group in favor of another.
